I don't have access to them anymore unfortunately but SM123 is still a fairly easy module, although a lot more physics than s111 which is always good! Don't get complacent though, I've just started S217 and the difficulty certainly ramps up!I'd recommend brushing up on some basic python programming for SM123, as if you're new to it as I was, then it can take up a lot of time getting to grips with it.
