I'm entering year 13 and applying for cambridge maths and I'm predicted 4 A* in maths, further maths, physics, chem, however I find chemistry slightly more difficult than the other 3 and I'm concerned I'm gonna have to spend a lot of time revising for it when I could instead be preparing for STEP. Do you think it will affect my chance of getting an offer if I drop it? Maths, further maths and physics are all very similar subjects so I'm not sure if they would kinda expect me to do 1 more.
