    Surprisingly, this has been my favourite science exam so far.

    I didn't really like that exam, struggled with quite a few questions and just found out about some (pretty big) mistakes i made. what did everybody get for the final question on the titration vs precipitation q?

    forgot to talk abuout breaking and making bonds on the last 6 marker

    hated that question about what experiments should she do..

    Otherwise it was okay, not the best, prefererred it to 2015 though.

    Yeah, luckily I remembered to do that but it was just the silly one markers that really wound me up (especially at the end)

    I'm exceedingly happy because the exam went well for me. I do agree though, the questions were phrased really ambiguously so anything could happen.

    Ironically enough, that was the one question that I guessed the answer to because I didn't want to waste time on it seeing as it was a one marker. I've seemed to have forgotten the phrasing of the question, what was it?

    Yup same i don't like additional science, especially after today's exam it wasn't awful but i just thought it was unfair that they didn't cover the key topics. I did well on the 6 markers i think, but the other 1/2/3 markers i strugged with. I'm officially worried now lol. Hate ocr more than i did yesterday

    Eurgh today's exam was mean. I didn't like it. I mean the 6 markers were pretty good, but the 2 and 3 markers like you said were awful! 2015s paper was a blessing, why couldn't we have had that

    Also OCR? Sort your spelling out

    No way was it really chlorine? I put that (I did keep it though luckily) but it really confused me as chlorine's poisonous and irritates eyes? Lol great stuff sunglasses company

    Glad someone feels the same way :/ I had no clue what I was doing. I've definitely got the last question wrong and the first page was nasty. I completely messed up some of the equations too. Uuuh i'm so disappointed. We still have C7

    They don't deserve capitals :no:

    I really liked that paper funnily enough, a couple things were confusing but not too bad. Did you have to discuss bonds forming vs breaking on the last 6 marker, as im sure that is part of C7. I simply discussed what the graphs showed and what it meant in terms of energy

    Bonds aren't mentioned in 4,5,6 so I'm presuming not

    yeah thats what i thought. i mentioned the fact exothermic give out energy etc and then what endothermic do. I didn't link it to the table of energy changes though

    Did you talk about conducting electricity?


    Posted from TSR Mobile
    I said that the salt can't conduct electricity and heat because the electrons aren't free to move but the dissolved salt can because the electrons are free to move. However, I know its the ions and not the electrons n an ionic compound. How many marks would I get for saying electrons?
