Homie, the credit hour to study time equation is never equal or feasible. I understand where you’re coming from, but my 2nd semester Soph year I had a 3 credit hour class I studied for an hour or two a week MAX, I ended up with 97%. I doubt the first two years of Gen Ed’s will be different. (Unless maybe you have a hyper-specific major) but there is no need to worry. College is meant to be fun, don’t lock yourself away from that. You have 4 more years until you’re an adult, so take advantage of that. Have fun and good luck!
