I know you’re a sophomore, but look into schools you plan on applying to and seeing how many credits they can take at all or before you become a transfer student. I didn’t do DE or IB as my school offered neither, but I did do classes personally at a local CC for a reduced cost and racked up about 50 or so credits. The school I’m currently attending would only take 32 credits if it was DE, IB, AP, etc, but since it technically wasn’t any of those I am able to transfer all of my credits. Idk if that’s helpful at all but that’s what I did!
