UM's biomed course is only 3 years course, and even SG doesn't recognize their degree (I heard it from Biomed frens,not sure though). UKM's was once accredited but the accredition was abolished few years ago cuz Ukm changed their syllabus from 4 years course to 3 years course. They are trying to apply for IBMS accredition again now. While for UPM's, I'm not sure bout it, but I guess UPM's biomed course is the best among these 3 unis. correct me if I'm wrong.

Ps : If u want to check for the IBMS accredition, U can try to look for on their website.
