Past paper questions - A level

I'm doing biology and chemistry past paper questions and I'm getting soo many questions wrong!
I'm getting a U in a biology paper 1 and I only have a few weeks until a level. Last minute advice is appreciated!

Hi, it’s probably exam technique that is a problem. I would recommend checking out the YouTuber miss estruch biology as she will definitely help you with exam technique. and for chemistry use save my exams and guided workbooks e.g those by cgp and also allery chemistry YouTube
