Got my TOEFL scores today. Scored 111/120. Reading: 29/30, Writing, 28/30, Speaking: 27/30, Listening: 27/30. This is all because of the TST prep. Thanks TST prep for providing me with high scoring templates and unvaluable tips.

It was an awesome platform as everything is broken down in digestible bits. I used it mostly for speaking. I saw the videos for all the questions and took notes and practiced questions from their website. Rest all I used the practice test section and full both on the yt channel. Thank you so much TST! I got 28/30 in speaking and 116/120 in total!

Delightful instructors, very helpful and considerate and above all fully practical - catering to the needs of millions while ensuring each individuals' goals are met. Helped me attain a perfect 120 as I'd desired. The best, sounds too good to be true but you really don't need anyone else!

I bought the score builder course and private lessons from TST Prep. Not only the learning materials are useful but also the tutors are very professional. After practicing for four months (I am a slow learner with ADHD), I got an overall score of 111 (R: 30; L:30; S:23; W: 28). Especially my writing section improved from 21 to 28. I will recommend this website to all test takers.
