It is true that you will progress faster here than at university. The reason is simple, our class sizes. At university you will usually be in a class with 20 or 30 other students, there will be little opportunity for you to speak up, and the teachers attention will be spread thin across all of your classmates. There is no personal focus, unlike LTL, where you will form a close bond with your teacher and they will be able to adapt the teaching to your learning style. Also, classes at LTL are between 5 and 10 minutes longer per class, over the course of a semester that also adds up.
