Local community colleges offer those classes. If you want to take it online, there are some reputable online schools such as phoenix, devry and capella. I think the tuition fee for taking it online is a little bit pricey.
They are almost 2 times higher than taking it in a local community college. Unless you are in military, I recommend you to take a traditional class in your community college rather than taking it online. I took several online classes last year, but the teachers in my online classes were not very helpful and I had to do all my work by my own without any help from them.
You could take a late night class if you work in the morning.. If you have any other question, please let me know!
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.
