I managed to score 120/120 with just about a week of preparation, and TST Prep played a huge role in that. The Emergency Course really helped to get familiar with the test and the mock tests were especially helpful because they were at the same difficulty level as the real test.
That said, even if you don’t want to buy a course, TST Prep’s YouTube videos are just as good, especially if your English is already quite strong and you mainly need to get used to the test structure.
