    For the Group 2 revision guide when you say “The same effect will happen to a lesser extent
    with metals going up the group as the solubility increases.” Doesn’t the solubility increase as you go down the group?

    I’m currently resitting my Alevel chemistry and have almost forgotten all the content but thanks to your notes I’m feeling more prepared for the exams by the day. Thank you so much, all the notes are extremely useful

    Hi Sir, you used to teach me chemistry back when I used to go Bancroft’s before sixth form, and now I’m very stuck on OCR Paper 3, because despite knowing most of the content pretty well, I find it hard to spot “synoptic links”
    These revision notes have been a godsend for learning the content, but I think I’m mainly stuck on exam technique, what would you recommend??
    Thanks,

    Kind regards,

    Meera

      Hi Meera, Good to hear from you. OCR paper 3 was a difficult paper. There is no substitute for doing as many past paper questions as you can and repeatedly reading notes so you know the syllabus inside out. Then when you come across an unusual question you have the confidence to know it must be an application of something you know and not to start making up chemistry. For example on the OCR paper 3 in the question about thiols you have to keep relating it back to your knowledge of alcohols.

        Ah, I see, that’s what I’ve been trying to do, but one of the later questions on 2017 paper 3 just stressed me out so much, it managed to combine transition metals with organic synthesis, and just knowing the colours off by heart didn’t help under timed conditions. Do you know if there are any useful websites with past topic questions that’s relevant to OCR A for the new spec? I just don’t want to learn something that’s not on this spec when I could be consolidating topics that are likely to come up.
        Like I’ve memorized anything there is to memorize through flash card and mindmaps, which proved helpful for paper 1 and paper 2, but paper 3 is definitely my weakness, so I’m just getting pretty stressed trying to do as much revision as possible.
        I need at least an A in chemistry, but, being my favourite subject, an A* would be so satisfying. 🙂
        Thanks for replying, sir.
        Kind regards,

        Meera

        What they are trying to do is create questions that are unusual that can’t be answered from looking at previous past papers and memorising mark schemes. That said looking at similar questions will help get you used to the type of thinking required. Old OCR papers should be useful. You can also look on AQA and EDexcel papers for the new syllabus. There is not that much difference between syllabi now.

        Okay sir, thanks so much, I shall do that within study leave, and see if it helps me get to grips with paper 3

    Hey chem revise do you have a guide on how to approach the common types of calculation questions (and or types of calculations that could come up in the exam)? I’ve noticed that the ocr a exam board are including a lot more challenging calculation questions which require a lot more steps then the old spec exams. I’m finding them difficult to answer – I did the 2017 papers in class and scored badly on the complex calculation questions in paper 1. I was wondering if you have any particular resources/advice that could help me with this problem.

    Thank you,

    Kind Regards

        OMG the questions in the textbook are amazing. I only had brief look atm but I’ve spotted some ques that actually came up in the 2017 exam paper 😀 eg. There’s a question in the shapes of molecules guide which asks to draw AlH4- this was a tricky question that came up in paper 1. Thank you so much sir looking forward to using them in my studies!

  5. i love chemrevise

    I’d just like to say thank you for making these revision guides. It has saved a lot of time in my revision and I like how it cuts straight to the point. It’s easy to read and understand.

    when will the revision notes for the new 2015 specification of OCR A chemistry be up. How different is the new OCR A specification compared to the old one. Thank you for producing these notes they are really helpful and i am able to grasp and understand things more better. all due to the fantastic notes you have produced.

        What differences are there specifically from the old and new spec? Also, are there many differences between ocr and AQA? Thanks, your revision guides are very good

        Hello, thank you sir for your help. Can you please send me the link for OCR A Chemistry starting from Sept 2015. thank you

    Hi thank you so much – extremely helpful!!
    Will you be doing notes for the new OCR September 2015 spec ?
    Thank you very very much :)))))

    Hi, your notes are fab, thanks so much. However, for the f322 module 4, in the equation about ozone depletion, it says CLO.(dot for radical) + O.

    Surely only one of them can be a radical? Thanks again, you are amazing!!!

      I think I am right with the dots (in that all the substances written with them are radicals) but OCR don’t require you to write any dots with the equation.s.

    i want to donate some money perhaps. these notes are outstanding. i have done similar notes on OCR A which took me a year to make them because i was making sure to get all answers from mark scheme and then use them in my notes.

      No I have not done notes for the OCR B. A lot of the chemistry is similar to OCR A but the structure of the course is very different. There is some content unique to OCR B
