I got 9,8,7s across the board but I spent my last month of gcse revision time on getting my art gcse up to scratch otherwise I would have failed. As a result i did terrible in my sciences which i thought were safe at, at least 7s. I wanted to go to oxbridge and i am going to do STEM heavy a- levels. Should i resit for better grades? I am really really ashamed and depressed at how badly i did as well. I got two grade 6s in biology and physics.
