I think you should do the one that is more conveniant for you casue you can always take classes while you work, thats if you wana persue more. Thats what I do right now I have one class and thats for aircraft structure, its only 2 days a week and realy if I want I dont even have to show up just get good grades 0n the tests and do all the lab work. But its funn goin in twice a week.
