    I might Go with the optional topic (astrophysics) because I'm waking up at 5 to cover everything on that so it'll be fresh in my head

    I'll probably do Astro first, there's only 5 marks difference between the two papers and I know I can get higher in Astro

    it did makes me confused too.

    But i just remember it like If it ask about energy released, neutron get into play. But when it asking about binding energy, only care about the nucleus.

    I dont know why, But i just do it in this way

    Good luck everyone, thanks for all the help you've given me! Just a quick question, on the grade boundaries it gives marks for an A on each section, what happens if you achieve the overall marks for an A but don't achieve the marks on one of the sections?

    Yeah there's two versions of the conversion. Ones dated and ones not. I think 931.5 is the most recent? Either way, just use which ever one is on the formula sheet in the exam.
