Re: Reading about people's views on A level Chemistry is worrying me!
Just to add one thing people haven't said so far....
As someone who has done AQA chem, bio and physics, I found chemistry to be the hardest of the lot, and part of the reason was that in the first module you learn that almost the entirety of what you learned at GCSE was incorrect to the extent that you have to unlearn it in order to progress. For example: electron shells as discrete entities don't really exist (or rather they overlap a lot at higher levels), Valency can be essentially ignored a lot of the time, water does not have a neutral pH etc. etc.
The biggest problem is that unlike in physics, where you essentially just learn when specific formulae apply, and biology, where you just learn a big ol' list of facts, in chemistry you have to take stuff that you learn in one context and apply it in a much more complicated setting to derive an answer. A lot of people try to just learn massive sheets of equations, and on exam day they invariably panic when something similar comes up and they haven't bothered to actually comprehend all the equations you learned.
It was really quite difficult for me, and the two biggest bits of advice I can give are that 1. if you didn't get at least a VERY high A (borderline A*) then you will have trouble (a few people in my class had Bs, and they'd all dropped out by A2 year), and that you really have to be willing to seek help when you don't understand something, because if you are at all sketchy about topics at the beginning you will find that it snowballs and you will have a lot of work to do at the end (true of any subject, but in my experience especially true of chemistry).
Good luck! -
Re: Reading about people's views on A level Chemistry is worrying me!I know the exam board is ocr, so I'll probably get a book in the next few weeks so I'm prepared. ;D(Original post by Dan12)
once you know where you're going, ask about the exam board you'll be doing and then I'd start straight away. You'll be surprised with the amount of people who cram stuff in in January and I'd rather be calm and relaxed in January or June so I can perform to my best. One other thing, make sure you drink plenty of water, do physical exercise and have healthy diet.
Good luck with doing chemistry and with your results in August. From what I've read, you seem like a dedicated, keen student so you should be fine.
Thanks for the advice, and good luck if you're awaiting any results as well. :-) -
Re: Reading about people's views on A level Chemistry is worrying me!Thanks, if you've got any questions during the next two years, I'll be happy to help. What really annoys me is the students who do no work for an exam and then complain about it after, and blame the teacher.(Original post by Deziah)

are you doing ocr biology as well if you are, buy the book and start asap. Also, when you're preparing for your exams, do every single paper available to you for that exam board (I learnt this the hard way) because in one of my bio questions, they copied one question that was set in 2003 and modified the last part. -
Re: Reading about people's views on A level Chemistry is worrying me!Aw, thanks. :-)(Original post by Dan12)

People did that a lot at GCSE, was so annoying haha.
Already ahead of you, got the ocr biology book. ;D
I've started learning about the organelles, and getting to grips with some of the words, probably pronouncing them wrong haha. -
Re: Reading about people's views on A level Chemistry is worrying me!good and make sure you learn ALL the definitions because they are easy marks. For F321 (unit 1 chemistry) the definitions that always come up is fits ionisation energy, relative atomic mass and others. LEARN ALL DEFINITIONS. Personally I preferred unit 2 bio at AS than unit 1 at AS. I also prefer A2 to AS where you learn about the detail of respiration and photosynthesis (in unit 1 A2). i think I probably still pronounce the words wrong but i just say the words how I'd write it (dunno if that makes sense).(Original post by Deziah)

Re: Reading about people's views on A level Chemistry is worrying me!
Changes between people but it's quite hard in terms of being a jump up from GCSE.
For me personally I found my A Levels hardest increasingly in order of wordiness. Biology was very much one which required you write out key phrases exactly, thus if you didn't put them down correctly even if you were correct you didn't get the marks, it was a case of remembering the key answers. Maths is the opposite, you either understand how the equations work and when to use them or not thus if you got the correct answer in anyway you got the marks. Chemistry is half way between the two, there are mathsy and wordy questions so it's a good mix. Conceptually none are particularly difficult. -
Re: Reading about people's views on A level Chemistry is worrying me!
its fine
I love it tbh
Biology is sooo much harder tbh, though Chemistry can be quite a big jump from GCSE. i've just started my A2 chemistry course and get seems the Chemistry gets alot more mathsy in A2( Rate equations,pH calculations,equilibrium constants and thats just in unit 4 of 6, But if you are good at maths you should find those concepts easy to grasp. The only thing lame about chemistry is the dreaded ISA on the AQA exam board which involves an assessed practical alongside a written exam.
Anyway GL

Re: Reading about people's views on A level Chemistry is worrying me!
Dw, they ease you into it. Unit does start slow! There is one GOLDEN rule to passing chem. Fall behind? get help!
Sometime during the easter term of AS i got sick and take almost two months off. Couldnt catch up on my own and too embarassed to ask for help. Result? I was still behind all the way until the summer term of A2 when i was revising for my June A2's.
I think chemsitry has a good balance of memorising but also of solving things. Its like the perfect balance between bio and maths. (Maths in the sense of problem solving rather then ectual calcualtions. Apart from titrations and EMF theres not too many numbers to deal with in chemistry!) -
Re: Reading about people's views on A level Chemistry is worrying me!
I really don't understand the people saying Biology is harder than Chemistry? I found Chemistry AS (dropped it after doing the AS, couldn't take doing a full A-Level), WAY harder than Biology. Biology, for me at least, was always the subject that required the least work and thought to get good grades, as the mark schemes accept almost anything. Chemistry mark schemes always felt very pedantic
.
It must depend on the way you answer questions I guess: if you go into lots of detail in your answers, and indeed if you know the syllabus in lots of detail, Chemistry is probably more suited to you; if you find you are better at applying what you've been taught to more unusual situations, Biology is probably better for you? I haven't looked at a Chemistry paper in over a year, so I may be remembering it wrong.
I should also add that I didn't do very much revision for my AS level Chemistry because I didn't enjoy it :P. That might have contributed to lower grades somewhat... -
Re: Reading about people's views on A level Chemistry is worrying me!Lol you are fogeting all the mole calculation equations:(Original post by sanaindaclub)

percentage yield= theoretical/actual
m=mass/mr
m= vol/1000X C
PV=NRT
the 3 energetics equations( though you can just use hess cycles)
And thats just AS lol A2 has alot more maths than AS.
The first topic of A2 AQA is Quantitative Kinetics so its an all maths topic followed by quantitative equilibria and acids and bases.
all in all its about 20% maths in AS and probly about 40% at A2Last edited by cuckoo99; 24-06-2012 at 10:19. -
Re: Reading about people's views on A level Chemistry is worrying me!
I liked AS Chemistry. If you get an A in GCSE Science, it's not hard at all. If you get a D obviously you're not going to get it. The only reason why I didn't carry it on to A2 Level is because it does require work. You need to properly revise and put effort into it, I knew I'd have a much easier time doing the Arts.

Re: Reading about people's views on A level Chemistry is worrying me!I will be doing OCR Salters A-level Chemistry. How hard will OCR Salters A-level Chemistry be for me in comparision to other exam boards? Shall I even pick it?(Original post by Cognition)
OCR Salters Chemistry was a nightmare! don't know about other exam boards! good luck!
I'm willing to spend a lot of revision time on it.

Re: Reading about people's views on A level Chemistry is worrying me!Personally, I don't think you should base your decision on the exam boards - there can't be that much difference between them, surely? Otherwise there would be people with "harder-earned" Chemistry A Levels than others? (But just for reference, I'm doing OCR Salters B and I'm still alive...)(Original post by krisshP)

The most important part is that you say you're willing to spend a lot of revision time on it. I am a firm believer that no matter how much you think you don't get it, after putting in enough effort and getting any necessary help, you definitely will get it. Stick to this mindset and you'll be fine

Re: Reading about people's views on A level Chemistry is worrying me!I'm Salters (have started A2 now) and I didn't find it that bad. As I said before, just make sure you keep up with it and ask if you're stuck. Tbh, it's really not worth getting your self worked up over how hard it may be. If you like it (and it's good for whatever uni course you want to do), do it. You'll be fine.(Original post by krisshP)

Re: Reading about people's views on A level Chemistry is worrying me!
It's certainly not the hardest A-level. Compared to Physics anyway. There's a lot of memorisation involved when it comes to equations and definitions. It's entirely doable if you put the time in. Also there's a fair bit more maths involved at A-level chemistry than GCSE.

Re: Reading about people's views on A level Chemistry is worrying me!The OCR salters concepts aren't hard (coming from someone who has just finished A2s) the hard thing about Salters is that the exams, especially A2 are really left-field. You could learn the entire syllabus, then they apply it in a way you don't recognise in the exam, and you're F*****. However, it's fine once you have done practice papers, AS i did none, and it was horrific, A2 it was basically all I did, and I didn't find it too bad - at least I was prepared for the left-field exam questions...(Original post by krisshP)
