So I have my ccea GCSE SAS Physics exam coming up in November and tomorrow we have a class test on it. We only started learning this in September so why we have to do the exam and risk failing in November is beyond me. My teacher only went through radiactivity a tiny bit last week and she expects us now to know everything about it and it's on the class test. I'm still revising household electricity because I'm scared to move on just in case I start to forget things. What should I do?
What do you wish you'd been taught?
