I’m doing S1 and S2 and I, along with most people in my class, really do think S2 is a lot easier than S1. S1 is just really wordy and sneaky, but S2 is so straight forward you just learn the formulas and that’s it. People who have done S1, M1 and S2 in my school think that M1 is the hardest out of them and, not that S1 is ‘difficult’ but just a bit weird, whilst S2 makes a lot more sense. I don’t really know how to explain it lol but I average 90 UMS in S1 and near 100 in S2 and this could all be subjective.
