also, anyone struggling to calculate their UMS/how many more marks they need for a certain grade, this link is EXTREMELY HELPFUL

dont forget to choose 'maths 6 spec' for maths since the grades are calculated differently from normal 6 unit specs.
and for reference, the f321,f322,f323 etc series is a 6 unit spec !!! but hopefully you knew that..... :smile:

Yeah I got that, only question I wasn't sure about was the 3 marks about elements in the periodic table. Which was the lowest boiling point?

I put neon, I think I put sodium for the lowest first I.E. then silicon for the lowest 4th I.E. because it was 4 a long from sodium, then neon?

Oh wow I'm literally so annoyed at myself for some of the stupid mistakes I made. I forgot to times by 2 for the Avogadro question and I messed up the 4 mark mass calculation, relative energy thing and drawing n2 as well as many more I'm sure and everyone is saying how easy it was and that they got an A for sure and everyone seems to get an A and I feel so stupid
