Getting 4.0 does not really guarantee your spot in the course u want. But u have a very high chance. U have to go through interview.
Yes U can opt for private universities if u didn’t get a place in public uni.
Yes there are scholarship to go overseas sponsored by kpm and mybrainsc but that scholarship is to become lecturers for matrics. U are bonded to them for 8 yrs.
I am not sure about the fine but I think it’s around RM 2000 ++
Hope this helped.
