liminalesque i did the exam this year.. so idk about other people but for maths and numerical, i found it really easy to do, only guessed about 2 and was within the time limit, so just revise yr 8 and yr 9 mathematics. For science, there were a couple of analysing graphs questions, like carbon dating (i might've forgotten correct me if i'm wrong), etc. For science report, the topic was how the soil affects plant growth or smth like that and we got results so you should be fine if you know the structure. For science information essay, the topic was antibiotic resistance and we got some information from a sheet of paper, I lwk did terrible but if you're good at science, you should be fine. Good luck!
