I really love TST PREP because their Emergency TOEFL course helped me A TON when preparing to take the test. In fact i only had 2 weeks to get myself ready for it but thanks to this jam-packed course I was able to get 103/120. My only criticism is maybe to improve last part of the course, the writing one. I don’t have any specific recommendations in mind, it’s just that the writing task in the TOEFL really dragged my score down ( i got 21/30 🙁 while on the other tasks 28×2 reading and listening, 26 speaking)
