Guess what! I done my 1st paper this Monday and it is eaaaaaaasy!!!!!
Nothing to worry about, I am doing Further Additional Science but the ISA is based on Biology; something to do with germination (can't say much sorry). But practice writing the variables and method and risk assessments as these come in one 9 mark question. It is really easy to get an A* or an A if your just practice. It is out of 20 so don't stress.
I tried to give as much concise info, I apologise. PM me if you like for further questions. I'll be happy to help.
