Is it efficient to use mcat biology books for imat?
It depends on your knowledge.
The important thing is to cover all of the subjects mentioned in the syllabus. You can do it either by watching youtube videos, or studying from a book that you feel like it’s more relevant for the imat and you feel like it’s better for you.
The MCAT syllabus is too detailed compared to the IMAT, it might be a waste of time at this point. IB and SAT would make more sense.
