Once you get one B you mathematically cannot get a 4.0. You must mean weighted score, California UC's want unweighted scores plus they will give you extra weight for 8 semesters of AP classes. The major thing you have to do is to score high on the SAT i.e.
Over 2200. You have a chance but there is no way to know until you have an ACT or SAT score.
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.
