It would take you two semesters to earn 30 credits. Full time studnets can take 12-18 credits each semester. Not all classes are worth 3 credits.
Just meeting requirements doesn't mean you will be accepted You do not need to go direct from school A to school B. You can take time off in between.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
