AS+A2 Biology this June - possible?

You want to learn 2 years worth of stuff in 5 months ?

I'm not doing anything with my time, so yes. Is it possible?

If I'm honest. I'm not sure it is. You have to like divide your time 2 and a half months for AS and then the same for A2 content. Not understanding concepts first time round will delay you as well.

What exam board are you thinking? I recommend you have a look at the specification. Maybe take some books out see what you think of the difficulty. I wouldn't be able to do it but everyone's different, you'll have to do some research.

You'll also have to organise to do practicals on top of that somewhere.

Thanks for the info, but I do not mean whether it's doable work-wise, what I mean is that does the specification allow you to do both in one year?

I don't see why not. It's not unheard of people doing A levels in one year. To be sure though I'd decide on which exam board you want to do (whether you want to do OCR or AQA etc) then have a look on their website or send them an email. I can't see why it should be a problem.
