    A General A Level Question - Will My Overall A Level Grade be affected by this?

    P1 MCQ's preparation thread for chemistry ONLY!!!!

    Guys I'm a bit worried about Chem MCQ :/ When I solve past papers, sometimes I get around 30-35 which isn't bad, but in the next paper I'd get something as low as 24! :/ I revise constantly, but this still happens, does anybody have any tips?

    Why don't you just study? I understand that MCQ chemistry is very tricky, but if you study hard enough I'm sure everything will go fine. You don't have to resort to cheating.

    Chemistry and Physics AS paper 12 MCQS

    Why is it C? The answer is supposed to be C but it doesn't make sense to me. 1g/2 = 0.5moles of H2. 05 moles * 6.02 * 10^23 = 3.01 * 10^23
