I recently got my A Level grades (IAL) for maths and physics. I got an A* in maths (198/200 in C34 in one sitting) and a B in physics. I plan to get an A* in further maths too (if everything works out well, I already have a 100/100 in S2). But my grade in physics wasn't what I wanted (I got a B), so I will take biology this year. Does anyone know if I have any chance of getting into top universities like Cambridge or Oxford (I want to study mathematics) with 2A* and a B (if my biology grade isn't A)?
