so i start school sept 1, im wondering how many credits i should take ( i work full time) i am only allowed to take core classes. epi, behv, biostats and envr. can it be done to take all 12 in the same semester? or should i just take 6? i really cant wait to get my MPH and become competitive in the work world (just got laid off last week) and be capable of working and doing what i want with passion. Im tired of working jobs i really dont like.
