Hi everyone! So i just graduated from high school. I really want to go to cosmetology school but my parents are making me go to a semester of college first to get the feel because I changed my mind. Well I forgot about the deadline for registration to pay my tuition, I swear I didn't do it on purpose! Anyway they emailed me and said that my classes have been dropped and I can re-register if I pay a 100$ re-registration fee plus the balance of 200$ that's in my account. I don't know how to tell my parents because I know they will be really mad. What do you guys think I should do, should I pay to re-register or convince my parents to let me just go straight to cosmetology school? I know this isn't really like health related or anything I just really need help:(
