I wasn't trying to get sh+tted on, the reason I asked, was I work full time I help my family out and going back to school for a year without work is just not financially feasible for me. Yes, If i am in dental school it makes sense because I'M IN DENTAL SCHOOL. but just going back to school while i have a great job in the government and attempting to go to dental (because its not guaranteed just wont work. I'll lose my great job, i'll be poor as hell and will have to wait until the next year to reapply. if i was 21, 22, 23 it would make sense, but I'm 26. thats why i was asking, if i could substitute those courses for upper level bio courses (because my university offers those at night and evening) and i could easily do it.
