Summer Class

I've read the guidelines on how the enlistment of subjects works.
What i think should be included sana is pwede ma enlist yung current subjects incase na ma ibagsak.The enlistment process kasi is that the current subjects are assume passed na .So,kung yung yung enlisted courses mo for summer ay prerequisites ng current subject mo na alanganin na,di mo rin sya matatake😅😔😔
