Is it possible to study AS Chemistry in the summer holidays (2 months?)Watch
I study Biology, Chemistry and Maths at the moment, I'm also in Year 12. I'm gonna go out on a limb and say that, if you were to teach yourself the course, it may be doable (to a good standard, as in B or above) within 3-4 months.
2 months is a very, very risky stretch for a 1-year course that you are to be taught by teachers, not to mention end of chapter/topic assessments. You may be able to catch up sometime in Year 13, that is if you manage your time immaculately.
I personally wouldn't go for it; and if I was to, then I'd start now, rather than waiting until the holidays.
Best of luck :j
In comparison to biology, which like you said has not gotten all that much harder, chemistry is definitely a lot more intricate and demanding - it's even more knowledge-based than it was in GCSE.
You get introduced to new and somewhat challenging concepts in organic chemistry, which build greatly on your understanding of organic molecules, ability to work with skeletal formulae, memorising and recalling reactions, mechanisms and conditions necessary for reactions. I'd say it is definitely harder than Biology, of which the most difficult concept so far (in my view) has been protein synthesis.
If you are seriously considering devoting yourself to it, then you'll have to be consequential with yourself, because that's the only person you'll be working for. I'd recommend getting help from teachers/knowledgeable people on the topic, perhaps even Year 13 students.
Feel free to pm/ask more questions in this thread if you have any :P
