Answer GCSE is not important at all, it is not looked at when applying to university. The important qualification is the one you receive after completing the last to years of secondary school (ie: sixth form), this can be IB, A-levels, etc I recommend that for GCSE you still keep your choices open, as you might not want to become a vet in 2-3 years! If I were you, I would chose Double Award Science (or minimum two sciences), Mathematics, and every other standard subject.
Try to get good grades When you move to sixth form, and you still want to become a vet, then you will need to concentrate your studies on science. TO DO A MEDICAL DEGREE, YOU WILL NEED BIOLOGY AND CHEMISTRY:).
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.
