current igcse student

is it possible to finish AS bio and full A level math all in one year (year 12)? currently doing my igcse's and they're one of my strongest subject predicted 9's so i think i should be fine but i also need to know how big the jump is from igs to a levels thank youu

What else would you so doing during Year 12? Or would it just be AS level Biology and A level Mathematics (both years)?

nothing I just want to complete math full a level and as bio in year 12 because i have a chance to get into uni a year only but i wanna know if its doable

In that case it's absolutely doable. Most people do 3 A levels over two years. You'd be doing 1.5 A levels over one year. So the workload would effectively be the same.
Have you found any university courses you're interested in? Do their entry requirements say they'd accept 1 A level and 1 AS level?

thats a nice way to think about it but i heard math is a chunky one (especially with the added mechanics/stats)
yeah iv done some research but im still not really decided on a major

Understood. It's worth thinking of a Plan B in case you don't get into uni with those qualifications. Would you stay on into Year 13?
At the point you hope to start uni (when most people would be starting Year 13) you're likely to be 17. This can cause unis some problems. So check with any potential universities to ensure they can accept under 18s.

I can stay onto Year 13 but I'm not sure I want to
