The youtube videos were very informative about the structure of TOEFL exam. Separate videos for separate sections helped me focus on the specific sections. The practice questions were god-sent. I went through all of the 500 questions from all the sections and they prepared me perfectly to improve my scores. I had to retake TOEFL exam because I scored lower than required in reading section, so my scores went from 17 to 26 in reading section after retaking TOEFL. Those additional 10 points were because of TST Prep website and YT channel which I referred to during my preparation. Now my scores are perfect to dismiss any standing admission condition mentioned in my admit letter from a Canadian university.
