    Prove it. Some people are saying both others are saying not both. We can't be sure unless someone actually shows the question. Then we can all agree on one thing. But till then I'm gonna say no it didn't and we can agree to disagree.
    We don't have the paper but on Tuesday I will ask my chemistry teacher to see the paper (he might have it) and then we'll see

    If you drop a subject and keep its AS grade then that is worth 40% of UCAS tarrif rather than 50%.
    But if you carry onto doing the full A level then your As grade doesn't matter
    Oh damn it I never knew. So the grade you get in AS counts towards the tariffs?

    Ok guys, I believe that for the first 6 marker, there were 2 marks for drawing 2 products, 3 marks for mechanism (correct dipoles, correct curly arrows, correct intermediate and product) and then 1 mark for saying why one is made in higher amounts than the other!
    Or instead of drawing the two products it could have been to write the structural formulae of each :teehee:

    Yh and you won't lose marks for not putting both.
    Yh they will say something like ignore the second product. Or allow1 product.
    Anyway what did you get for the metal? Ca
    And as you go down group 2 miles decrease so vol decreases?
    Also was the mass in grams like 1.8....(forgot the rest)

    For most unis u need 3 a levels, so if you have a fourth AS and don't do the full A Level for that subject then only for that one

    Why would you write the structural formulae?

    Hope it's 'allow any type of formula'

    What did everyone get for the rate of reaction? 9x10^-4? And how many marks would I lose if I done everything right for the last question except drawing butanoic acid at the end?

    Don't get why you would write structural formulae for electrophilic substitution. You have to use displayed formula as you show the movement of a pair of electron to the positive carbon

    Oh that explains why people say to choose an easy 4th subject.

    Lol I slightly struggled with writing it out structurally much easier to draw it out.

    As I remember reading structural in the question and struggling to think on how to write it out lol. Structural formulae to show the end products.

    OK cool, then if you're right I'll happily admit I was wrong

    Unlikely based on the boundaries for the old specification.

    Read the section on 'Has anything been lowered'

    This is why I'm still a bit confused. As I know that AS does not count. Yet our AS papers are being mixed with A2 content?
    If you drop the subject then you get to keep you're AS grade, but if not then your AS grade does not mean anything for next year.
    Next year there are 3 papers:

    Periodic table, elements and physical chemistry(01)100 marks 2 hours 15 minutes written paper = 37%of total A level (assesses content from modules 1, 2, 3 and 5.)

    Synthesis and analytical techniques(02)100 marks 2 hours 15 minutes written paper = 37%of total A level (assesses content from modules 1, 2, 4 and 6.)

    Unified chemistry(03)70 marks 1 hour 30 minutes written paper = 26%of total A level (assesses content from all modules (1 to 6).)

    This year you've covered most of modules 1 2 3 and 4
    next year you will learn mainly 5 and 6 but also additional information from 1 2 3 and 4

    There is also the Practical Endorsement in chemistry(04)(non exam assessment) Reported separately. It requires a minimum of 12 practical activities to be completed from the Practical Activity Groups (PAGs)

    I got something*10^-4. If you didn't draw the final product but dos everything then that should be 5/6.

    Not for the mechanism, but cherx was talking about the final products

    for the last question, I ended up getting butanoic acid but my method was really weird and I used 89 instead of 88 etc, would I still get 4/6 marks for getting to that conclusion or no, is method looked at a lot?

    So there would never be any more MCQ? I quite liked the breadth and depth paper layout for chem.
    There will be multiple choice questions. That will be on all of the papers we do next year apart from the Unified Chemistry (all modules)
