Hi, I'm in year 13 and do bio, chem and pysch. Have you maybe had a look at any apprenticeship schemes? There are a lot out there so possibly have a look into those! If you're still set on doing A-levels, you could possibly look into foundation courses at Uni which tend to offer lower grade boundaries? A2 content mainly builds on your AS content and goes into a bit more depth, maybe over the summer you could try to focus on learning AS content and practicing exam questions that would put you in a great position for A2! Hope this is helpful!
