Do I need to apply for an entry permit if I have a Singapore student ID card?

yes.

Students who apply for IPA to enter Singapore for the first time need to apply for an "in-principle-AP-proval", which is the proof that the Immigration Department (ICA) has approved their entry. IPA is a single-entry visa.
