So I’m in year 12 and we have these monthly assessments (not rlly monthly bc we have to do them after we finish every topic) and I’ve done three so far for A level bio and chem and I failed all of them and got a U. I don’t think I have ever gotten a U so I was quite disheartened (ik it’s just a topic test) but can anyone recommend any revision tips or anything that will more or less help me improve my grade!!! Thanks
