It depends on which country you live in. In the US, to become a doctor, first you need to get a 4-year bachelors degree. Major in anything and take the premed classes in bio, chem, physics, math, and English.
You can do this at any 4-year college or university. Then you apply to medical school at a different university. You can easily find lists of them online.
That's another 4 years. And then after that you've got 3+ years of residency at another university/hospital (training).
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.
