UCs do not look at freshman grades. You do not need to take honors classes in your sophomore year to be accepted by a UC.
You have not ruined your chances of getting into any of the UCs, so do not fret. However, you need to change now! Start getting straight A's or else Berkeley and UCLA will soon disappear, and if your grades continue to suffer, San Diego will fall off your reach too.
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.
