    That's what I've been told by my teachers, but it will be good to clarify anyway
    Thanks for getting in touch, if you can quote me once you find out that'll be good to know
    OK - after a 10 email exchange with OCR it is as I thought.

    The AS and the A2 exams are independent of each other so that if you did AS in 2016 and got an A, then you did A2 in 2017 and got a B, you would get two certificates with the respective grades on because they are independent exams. As far as unis are concerned, of course only the A2 exam result counts.

    Hi, I am re-doing my AS Chemistry OCR Controlled assessments, and I really need to do well.

    Qual CA: • You will attempt to identify four unknown solutions; • You will investigate the effect of heat on three solid compounds.

    What would I need to know/go over, in order to do well (i.e. precipitation reactions?) PEASE REPLY ASAP AS IT IS URGENT...

    Really sorry! Only just seeing this!
    This thread is for the new specification that started this year, I haven't learnt anything about precipitation reactions as yet, so not sure if this group is much help

    There is a chemistry teacher about that might be able to help you on this thread though?

    I hate to be brazen but, surely it's common sense for those who have even basic literacy skills :borat:

    Furthermore, stating that the files are 'notes' (in the title) -- coupled with the course name and module classification -- should be fairly conclusive :stupid:

    Your comment on my basic literacy skills is greatly appreciated.

    I was just wondering why you had posted notes without any comment as to why you're posting them. It seemed very random.

    As far as how OCR might examine you goes, you are correct.

    Does anybody else use the henderson-hasselbalch equation for buffer pH calculations? Hopefully it will be fine.
