just thought I'd like to have an idea before going into year 13
firstly s2 is manageable and easy but grade boundaries are quite high usually .
C3 and C4 are of course harder than C1/2, but you have to remember you'll be more mathematically mature in 10 months so I'd like to say if you keep up the same work rate, whether that be big or small, that you had from AS that your C3/4 scores will be similar to your C1/2 scores.
Obviously its hard to say as it's kind of subjective i think

If you found C1/2 easy then C3/4 should be pretty much straight forward. If you struggled at C1/2 then you may be knackered for C3/4. S2 isn't terrible but it's very different to S1
