You have TOEFL exam coming up and do not know where to start? This channel is your answer!
I cannot thank this channel enough! I retook TOEFL in October 2024 year and scored 115 - 29 in Reading, Listening, and Writing, 28 in Speaking. This is 9 points higher than the previous year’s result (March 2023); both times I used TST Prep channel and now I recommend this content to everyone around me who is interested in taking TOEFL. Awesome work! TST Prep is a gem for everyone who is confused about the test and wants to prepare in a limited time.

I bought their emergency course and just had a few days to prepare for the TOEFL test. I did many of their exercises, watched all the 6.5h long emergency course and many videos in their YouTube channel, and scored 91 (previously 75 1 year before). My reading jumped from 13 to 24 (this was the piece I focused more btw).
I’m really grateful for the content Josh and his team published in the internet!

I scored 102/120 on my TOEFL exam and it was mainly due to Josh's videos on YouTube. He is well prepared and makes the videos easy to follow and understand. All the tips and templates, plus his overall experience on the matter really helped me prepare and get a feel as to how the exam would go.

Absolutely fantastic videos by Josh and his TST prep channel. Managed to score 102 solely (!) on his YouTube videos during one week. If I had more time I'm 💯 sure I would have scored more.
Highly recommend!

Detailed review of their products
The other reviews of this place are phenomenal and rightly so. I want to talk about the specific products by TST so you can decide which works best for you:
1) Free YouTube Videos: TST has free, comprehensive TOEFL-style questions on their YouTube channel. You can find at least four full tests (some are broken into parts in different videos) for FREE!
2) Free PDF Documents: Check the YouTube video descriptions for free PDFs, including templates for speaking and writing. Super helpful. I didn't memorise them but just got the gist to help structure my response. Please look for documents like "100 Independent Speaking Questions" and "100 Listening Questions". I found these pdf when I logged in to the TST websites. These PDFs are extremely high-yield for your prep.
3) Free Practice Questions: Please search on google or duckduckgo for "Practice questions for TOEFL speaking" to find a TST website with speaking questions (click submit sample button to see the full question), sample student responses, and teacher feedback. More free practice for speaking!
4) Paid Emergency Course: Now the paid options. For around $30 (with a coupon), the Emergency Course offers two full-length tests with sample answers and extra goodies like 20 listening lectures to practice fast note taking. It's cheaper compared to another company that sells practice tests. (I cannot mention that company because of Trust pilot guidelines). If you watched their Youtube free videos, you know their practice test are excellent! :-D
5) Speaking Evaluation: For $30, a TST teacher provides feedback on your speaking response. This helped me improve my score significantly, in a short time (I ended with a 29. I admit I started with a high score but the feedback helped me polish my skills). Highly recommended if you're struggling with the speaking section. Please get this well in advance so you have plenty of time to work on mistakes.
6) Writing Evaluation: Similar to the speaking evaluation, a TST teacher evaluates your writing response for $30. I got a 26 even though I lost a few points due to a problem while taking the exam at home :,) Here's the thing, AI can check your writing; however, there is a problem relying solely on AI without human evaluators as of 2025. AI can tell you your mistakes but it doesn't triage them. For instance AI will indicate many comma mistakes (argh!) and change sentence structures. But those aren't mistakes ETS examiners penalize extensively, it's just that AI prefers to write sentences in its stringent way which it learned from the internet. That's fine. But you might need a teacher to tell you which mistakes are blatantly obvious and which can be ignored as a difference in writing. You can skip this but if you want an experienced teacher to evaluate your TST writing please get help from the experts at TST.
Customer service: My emergency course test had a question that I already attempted in one of their free YouTube videos. I contacted TST and they helped immediately. So 10/10.
I hope this review is comprehensive enough. The free resources are a must for everyone, and the paid products are great for targeted practice. TST tests are necessary for prep, so going through 1-2 of their tests is essential for the exam, even with excellent English proficiency. Best of luck!
