My alevel options

I picked A-level biology, chemistry, physics, AS maths and an EPQ.
At first I didn't know whether to pick maths or phys but turns out my teacher suggested this was a course i could take.
My grades are 9 in bio, 8 in chem (3 marks away from a 9), and 9 in physics.

Is this a good choice to make, is it managable and what should I expect from taking these courses? Will it be too difficult to obtain higher grades if i take these courses combined?

Thank you for answering my questions

I think 4 a levels and an EPQ is going to be very difficult and means balancing your time effectively. The good thing is you can always drop an A level or EPQ if its to much. Best to speak to your teacher. What are you wanting to go into?

I did 3 a levels (bio, psych, History) and an EPQ. History had coursework which meant it was hard to do with the EPQ. If I was doing a fourth subject like English lit (which I was planning on doing) it wouldn’t have been possible. A levels are harder than GCSEs, please don’t understate this. Doing 4 and an EPQ will be very difficult- my school didn’t allow it.

I dropped my AS level in German to do an EPQ because doing both would be too much.

Also (from experience) Biology is hard!
