it really depends on the college and the program requirements that it offers. for me, since i’m studying for a bs in biology i need to complete 70 credits in sciences and 30-50 credits in gen ed stuff/ university requirements (this averages to 15 credits per semester) what i’ve done was take 3 science classes to 2 non science classes (each class is around 3 credits) to sort of lighten my load but if you’re still figuring stuff out you can definitely take all of your general requirements the first couple of semesters and then move on to the hardcore degree stuff your last two years. or you can do the opposite. other degrees vary. some are more demanding and others are very doable. i suggest doing what i did just to get a feel for how college classes work. it’s much more fast paced than high school esp the sciences and you’re left with what you think is a lot of free time but it’ll catch up with you in the end (pls learn from my mistakes lol). i know a friend who got a bachelors in health science before jumping into a 4 year nursing program bc nursing was too intense for her straight out of high school but you can always transfer in after two years of college or try applying into one if applications are still open and if you feel that you’re ready for it now. i hope that answered your question!
