My uni did not mention anything about me cannot enter and stay in malaysia before my commencement date. Besides i have told them i got interview waiting and Marathon at the end of January and they told me as long as I got the val and sev i can remain in Malaysia. Besides these counted feb and march are my semester break.
I wouldn’t recommend that. Most of the universities advise their students to reach a week prior to the commencement date. Your student pass validity is counted from the day it is issued and not from the day your classes begin.
