Self-teaching Chemistry A-level (as a private candidate)?

To cut a long story short, I'm considering applying for graduate medicine. As a law student, I don't have the required Chemistry A-level (nor Biology/Physics). I want to sit it as an external candidate, but can't afford to do the whole distance-learning-with-a-tutor business. I would need to self-teach.

To anybody who has experience of self-teaching Chemistry at A-level: is it do-able and how long did it take you? I have A*s in 3 sciences at GCSE and close on 100% in all of them, so science isn't (or at least, never used to be) something I struggled with.

Advice in this respect for biology, human biology and physics too would be appreciated, as I need to choose one of those alongside Chemistry. Do any of the three stand out as being more difficult than the rest?

Also, on a side note, are there any Chemistry/Biology/Physics A-levels which don't have practical exams, or do all exam boards require them? Much as practicals sound fun, they are also expensive to take as an external candidate so I'd rather avoid them if possible.

Hey. I just saw your post from 6 years ago, did you study medicine because am thinking doing medicine but don’t have much science except nursing degree. Any advice

Ask in better places than in reply to a 6-year-old post to someone who probably doesn't even post here any more.

What other places? I don’t know any that’s the problem. Do you know any.

I'm home studying biology, physics, chemistry and maths. I got AAAB in January with 1 mark away from am A in maths but I think I caught up in the May exams. You don't need to pay for distance learning courses they seem like a total waste of money as there are so many amazing resources online for free. The distance learning courses don't even set you up with exam centres so you'll still be completely on your own to organise them.

If you have money there's 3ATutors in Bristol that do practicals at £300 a pop, I know a place where you can do it for £100 so pm me if you want that info. As for the whole learning process here are some amazing resources (AQA focussed):

All you need to actually buy is the book and there's enough info here to get you 100% if you pay close enough attention to the syllabus and mark schemes.
