For future years/reference, the wording at the end of Question 1 on your sample exam is a bit misleading - it looks like you want us to compare the relative intensities of the (200) and the (400) peak for each sample ie) I(200, Ca)/I(400, Ca) whereas you actually want the relative intensities between the two samples, I(200, Ca)/I(200, CaF2) & I(400, Ca)/I(400, CaF2). Just a small thing but can be a bit misleading. Hopefully you understand what I mean - it is difficult trying to express so many subscripts without TeX!
