I have chosen 4 A levels which are Biology, chemistry, maths and psychology. Because my GCSE grades were very strong (10A* and 2As) my school allowed me to do 4 A levels. They insist on doing three because all the exams will be linear meaning that there will be no AS exams. so I'm quite confused because I think I've chosen all four hard subjects. Any advice or suggestions? -- keeping in mind that my future career plan is medicine.
