On the contrary, the classes are basically rote reading. The classmates will engage in a one way dialogue with the teacher and you as a “slower” student will be paid no attention. Actually, you´ll be the one at the right level… it is just that the others are way down to take it easy. Teachers like to deceive themselves that way.
AFAIK, nope, MTC doe snot offer intensive. Problem is the textbooks, lack of actual learning materials and overall approach top teaching and learning.
What all students say is that you go to MTC but you learn on your own, outside. MTC is for your right to be here on a visa.
I would recommend you not to go to MTC. NTU has intensive and non intensive. The intensive is managed with a foreign university and it is quite expensive but more worth it for your career.
