A teacher-monitored program for students who need more than automated scores and endless practice questions.
Exam coaching packages are available separately.
Sherlen Tanner, TOEFL coach 5,000+ students from 55+ countries. The AI was trained on my own teaching method, and I still review every member’s work myself.
LangSolution adds something automated practice cannot provide: an experienced teacher who reviews your progress every week and decides what you need to do next.
An AI will score your essay in two seconds and tell you it lacks development. That is not teaching, and it is not what is stopping you from reaching your score. What you are missing is someone who knows what your mistakes mean.
The platform runs on its own. These are the parts that do not run on their own. They are my responsibility.
I read your actual work every week. I read your essays and I listen to your recordings. I do not only look at your scores.
I tell you what the real problem is, even when it is not the one you thought you had.
I write your plan for the next seven days, and I tell you why each thing on it is there.
I read your work across weeks, not one piece at a time. A single essay can look fine. The same mistake in four of them is the thing worth telling you about.
I take work off your schedule when it will not help you. More practice is not always the answer, and it is my job to say so.
I keep adding new practice to the platform, so the content stays ahead of the exam rather than behind it.
I hold the membership at eighty people, because that is the number whose work I can read properly every week.
If a week goes by and you do not hear from me, something has gone wrong. Write to me and I will fix it.
If your English is already strong, a score and one line of advice are enough. You read lacks development. You know what development means, so you add it. Those platforms are designed for that student, even though they do not say so.
Everyone else reads the same line and cannot act on it. Not because they are slow, but because add more specific details is not a real instruction unless you already know which details to add and where to put them. The further you are from the score you need, the less an automated comment can do for you.
That gap is the reason this membership exists. The gap is largest for students in the middle, and that is where most of my members begin.
Years of teaching experienceBuilt into the learning system
Use a TOEFL platform created by an experienced teacher. Practice with AI trained on Sherlen’s proven TOEFL method, and receive personal guidance from Sherlen as you progress.
Her task strategies, teaching sequences, correction priorities and targeted practice sit underneath everything the platform gives you. The platform does not simply generate questions and general comments. It follows the method she teaches.
The system looks beyond a score and focuses on the specific skill that prevents improvement.
Students receive models, structured strategies, recall practice, re-speaking, and focused correction based on the task.
Students practice the corrected skill again and apply it under realistic TOEFL time limits.
Automated feedback is fast, and it is usually right. It can even tell you that your example does not match your reason. What it cannot tell you is which two ideas you have confused, or what to do about it. Here is the same Academic Discussion response, scored by an AI practice site and then read by me.
> Your example does not match the reason you gave. Use a more relevant example.
> Organization: clear progression from claim to illustration.
> Language use: minor errors that do not obscure meaning.
Sherlen’s weekly reviewMariam, your example is specific. It is specific about the wrong thing.
Your paragraph is well built. You make a claim, you illustrate it, and you close it. Your English is clean, and your example carries real detail. Most students cannot produce a detailed example at all, so do not lose that while you fix what is below.
Working in the same building helps a new employee learn a team’s unwritten rules faster.
In her first month she learned to restock the treatment room and file the weekly supply order.
Restocking a room is a practical routine. Unwritten rules are different things: who to ask, when to interrupt, and what the team never says out loud. Your story proves that in-person training is faster. It does not prove your claim, and because the story is so detailed, it ties your whole paragraph to the wrong argument. A vague example would have cost you fewer marks.
The 3 is correct, and the machine is right that something does not match. But use a more relevant example is not advice. It repeats the problem instead of showing you how to solve it. Relevant to what? There are exactly two ways to fix this, and the one you choose changes what you write next.
Two repairs, and you choose. Change the claim so it says what your story already proves, or keep the claim and replace the story with the week you did not know who to ask. I will not join them for you with connecting language. That would read smoothly and teach you nothing.
More questions do not guarantee improvement. You need the right learning tools, consistent practice, and someone who notices patterns over time.

LangSolution is not simply a test bank. It teaches students how to approach each TOEFL task, provides guided practice in Training mode, and gives students realistic practice in Test mode. Students can study their results, understand their mistakes, and use specific feedback to improve the next attempt.
Reading, Listening, Writing, and Speaking practices
Each section includes 60 practices: 6 weeks with 10 practices each.
A thousand random questions is a test bank. 240 practices, each built for one skill and one purpose, is a course.
You do not need more practice. You need the right practice.
Students do not have to guess how to read a TOEFL passage. The platform teaches the thinking process and then gives them structured opportunities to use it.
Listening practice begins with preparation. Students learn what to notice, listen when they are ready, and study both the transcript and the reasoning behind each answer.
Students receive more than a score. They learn how to build accurate sentences, complete every requirement, evaluate their own work, and understand the exact changes that can improve the next response.
Before students begin, they see a short task reminder and learn whether the email requires a formal or informal style.
The same guided process helps students select one student’s opinion, respond to it, and support their own position.
The brainstorm is generated from the question and the classmates actually on the page, never from a stored list, so the suggestions always fit the discussion in front of them.
Students write every sentence themselves, so they build the independent writing habit they need on test day.
The feedback explains what the student did well, identifies the problem that affects the score most, and separates major priorities from small language mistakes. Students can see whether they answered the task completely, developed one clear idea, organized the response effectively, and controlled grammar and vocabulary. Every essay ends with a practical direction for the next response, so students know what to correct before they write again.
The Speaking section develops performance step by step. Students first strengthen recall and response structure, then practice speaking to realistic prompts and study a report about their performance.
Every interview question has an Ideas button. It opens three complete sample answers, each taking a different direction, so a student who has nothing to say can hear what a finished response sounds like before they record.
Ideas give a direction to take. The words, the examples, and the recording are the student’s own.
The report shows more than whether an answer was correct. It explains what the student communicated clearly, where the response became incomplete or difficult to follow, and whether the main issue came from ideas, organization, recall, fluency, language, or delivery. The student receives a focused priority and an exact practice direction. This makes the next attempt purposeful instead of simply repeating another question.
Structured B2 to C2 practice helps students improve the sentence control they need for accurate speaking and writing.
B2 to C2 practice builds the vocabulary students need to understand academic material and express ideas precisely.
Daily drills use real TOEFL writing sentences. Students practice for at least 30 days, so typing becomes faster and more automatic.
These tools help students understand unfamiliar language, repair recurring weaknesses, and return to earlier feedback instead of losing it after one activity.
Every error the platform flags in a student’s own writing becomes a card. The card shows their sentence with the mistake marked in red. They type the correction, and the repaired sentence comes back with the fix in green. Fifteen cards at a time, so the same error stops travelling from one essay to the next.

Practice on your own and you will get scores. Practice inside a membership Sherlen watches and you will get a reason, a correction, and a plan for the week that follows.
Eighty is the number Sherlen can read properly every week. When the places are filled, enrollment closes until one opens.
Founder, LangSolution
I teach English, but international professionals do not come to me simply to learn English. They already have careers and expertise. They come to me because they want their English to reflect the level of expertise they already have.
For more than 20 years, I have worked with English learners and international professionals from many countries and professional backgrounds. Many of them are healthcare professionals preparing for licensure in the United States, and for them the TOEFL is not an academic exercise. It is the last thing standing between them and the career they have already trained for.
Seeing the limits of live coaching alone is what led me into educational technology, and eventually to building this platform. The teaching in it is mine. So is the weekly review you receive.
Read our success stories. You can be one of them.
Read the success stories →The new format arrived and most preparation material did not keep up. Every result below is from the new exam. These are not numbers I typed out. They are the score reports themselves, exactly as my students sent them to me, with their names covered.
Reading, Listening, Speaking and Writing, on the format used from January 2026.
Every image above is an unedited screenshot from the student. Names are covered, scores are not.
I stopped collecting portrait photographs and written testimonials in January 2026. The score report is the only proof that matters. On the new exam each section is reported out of 6 and the total out of 120. A 5.0 in Reading is not a five point score. It is the second highest band. Every student above reached CEFR C1.
Pharmacists, dentists and nurses who needed a TOEFL score to practise in the United States. Most had taken the exam many times before we met. These are their words, and their scores. Hundreds more passed and were never posted.
I tried many tutors before, but my scores did not change at all. Sherlen’s teaching methods ultimately worked for me. She tested me for every skill and wrote down my specific plan. She wanted to improve my reading and writing scores first. She was very flexible in teaching me. Whenever the method did not work for me, she tried a new one to help me get through it. After one month, I took a test and improved from 73 to 84. We worked together for another month, and I got my desired scores of 94 and 95. Reading: my score went up from 14 to 26; writing scores: 20 to 27. We did some classes on speaking, and my score went up from 20 to 22. Not only is she a good teacher, but she is also a responsible tutor. She cares more about the quality and my result than my money. I can’t explain what she did to help me win my TOEFL battle and I want to say a big “thank you.”
Thanks from the bottom of my heart Sherlen. You are a blessing to TOEFL students. Without you, I would have been stuck forever in this exam. I give you all the credit for getting Speaking 28 after being stuck at 23 for a long time.
My first TOEFL speaking score was 14. I have tried more than a dozen times to improve my scores. When I met Sherlen, I had hit the ceiling for two years in my score for speaking at 23-24. She coached me through some very challenging phonetics pronunciations, was honest with me, and very supportive. My final score for speaking was 26.
I finally took the TOEFL test, I ended up getting 102 at the end. My score went from 73 to 102, with 26 in Speaking, which was much higher than what I expected to have, so I’m really happy and blessed about that. A 26 in speaking allows me to apply to a university like Howard or Michigan. If you are a foreign dentist who is trying to apply to the international dental programs and you need a competitive score in TOEFL, I am pleased to highly recommend professor Sherlen. She will contribute greatly to your success as a dentist in the United States. It was an honor being your student!
For me, the toughest battle was the TOEFL exam. It was nothing complicated for me to pass the foreign pharmacy exam, but I got very intimidated by this exam, especially since I missed the speaking score four times. I got 27 after Sherlen’s classes.
Achieving a high Speaking score of 26 is the toughest challenge that foreign graduate pharmacists face when they plan of becoming a pharmacist here, in the United States. People keep trying and others give up after taking the exam six, thirteen, or twenty times. Recommending Sherlen for me after my wife read reviews about her had changed everything. I got 26 after her classes.
I was stuck in the speaking section for almost 2 years. I tried every method that online tutors recommended on YouTube channels, but I still failed. I didn’t know what I did wrong. She could indicate my problems in the first class we met. I took the test even before I finished the 1-month private class with her and I passed.
I am beyond grateful that she was my teacher for the past 3 months and I am very convinced that I could not have put the stress of TOEFL behind me this quickly if it wasn’t for her, and pass the exam on my very first try. The Writing Studio was for me the hardest. I was struggling on my Integrated essay, Sherlen was constantly giving me feedback and that’s how I was able to score 29. She has these very well-thought templates that she teaches that made the difference in the exam.
I am very happy that I am able to leave the TOEFL exam behind in 2022 and start a new chapter in my life in 2023. Board of pharmacy I am coming! She opened my eyes on many grammar and pronunciation mistakes and helped me to increase my score from 24-27 in speaking. She evaluates and tracks your skills during the course, and she makes sure that you are getting rid of your fossilized mistakes.
I tried to study TOEFL by myself. Yet, I failed. I tried to study with a different tutor, I failed. I tried to follow some “recommended” speaking templates, I still failed. I had no idea what I had done wrong, so finally I reached out to Sherlen again. I realized that no matter how good the speaking templates are, if you don’t have good pronunciation, you will never ever get a good speaking score. Sherlen didn’t try to keep me with just herself. She talked to my husband and guided him on how he could help me with my speaking. On June 15th, it was either my 8th or 9th time sitting at the test center. On June 25th, I got my result. I PASSED! I got 26 in speaking!
Since thenNui has started her new job as a licensed pharmacist.
Result Irina’s final score is 101 after 20 hours of classes with Sherlen in two months. She took the TOEFL exam only once.
Dear Sherlen! I am overflowing with joy. I was accepted to dental school of my dream and was selected from 1500 applicants to be a part of class that consists of 20 international trained dentists. It was extremely stressful and difficult process. TOEFL score was one of the decisive aspects dental school were looking at in order to extend interview invitations. I don’t even know what I did without your TOEFL personal classes. You are an amazing teacher who was accompanying me through the every single assignments during preparation. Thank you very much for your professionalism.
Eleven stories out of hundreds. Most of the students who finally passed never had their words posted anywhere.
These students worked with Sherlen in her private and group TOEFL classes. The teaching method behind their results is the same method built into this platform, and the weekly review you receive is written by the same teacher.
Two ways to work with Sherlen. Start with the membership, or add scheduled coaching on top of it.
Not just practice. A teacher reads your work every week.
Only 80 students can hold an active membership each month. Enrollment closes when all 80 places are filled.
Structured exam preparation with scheduled coaching, platform practice and progress guidance, built around your test date.
Coaching dates are confirmed with Sherlen before anything is paid, so you are never booked into a week she cannot cover.
No. The learning system was created by a teacher, and the AI is trained on Sherlen’s proven TOEFL method rather than a generic rubric. On top of that, Sherlen reads your work every week and writes your next plan herself. That part is not automated.
No. The $99 membership is platform practice plus Sherlen’s weekly review and your plan for the following week. If you want scheduled live coaching as well, choose one of the exam coaching packages instead.
Sherlen reviews your platform activity, your consistency, your practice patterns, your improvement, and the problems that keep repeating. She then adjusts the feedback the AI produced and assigns the practice you should do next.
Because Sherlen reads every member’s work personally. Eighty is the number she can review properly each week. When the places are filled, enrollment closes until a place opens.
