I think it depends on where and what do you want to study... If you do certain foundation at certain uni, you will have higher chances to get into that certain uni... e.g in UM, they call it Asasi... so if you get into asasi sains hayat, for example, you will have higher chance to enter related courses in UM, such as medicine, etc... They have their own evaluation system... my cousin did a foundation in msu, then he proceed to msu for degree. but there are still possibilities of getting into another uni, though - like me

correct me if I'm wrong
