    Got to @MaChemGuy on twitter, he has a spider diagram of all the reactions for AS and A2. Just keep drawing the diagrams out again and again

    Good call, great that he posts chem questions for causal revision whilst procrastinating

    You can't make it from hydrogen itself. You have to have an unsaturated plant oil. You vaporize it, pass it over a nickel catalyst at 60 degrees Celsius and add hydrogen.

    Why is importance placed on it being a plant oil?

    Because you cant make margarine from hydrogen. By hydrogen is just added to the oil. Plant oils are always used.

    Uh, because you're going to be eating the margarine after, so it's important that what you're using is edible?

    Honestly, I know it sounds cliche but flashcards ! !! !!!

    Just write the reaction on one side and the answer on the other side and test yourself, it honestly helps so much. Even the process of making the flashcards is a big help with memorisation.

    I've made flashcards for the whole of A2 chem and it's helped with not getting confused between similar reactions and reagents and what not!

    I'm in the same boat though, I got 90 something UMS and I'm hoping for an A so I can maybe get a B somehow
    I heard everyone found that Stats exam hard so don't worry about aha!

    Thanks so much for the help guys! I'll definitely try both of those techniques for Chemistry in general. Can't wait to be finished with Chemistry for good! It's just not my thing, unfortunately. I seem get C's or B's no matter how hard I try.

    Good luck with your revision.

    A Twitter post I saw about it said this:

    "#F321 predictions:
    Dative cov bond
    SIlver nitrate test
    Metallic bonding
    H-bonding diagram
    Reactivity down a group
    Water of crystalisation"

    I would just ensure my understanding of this but not totally tunnel vision on it
    Who was that tweet by? I would really like to know if there are any f322 predictions for tomorrow! Do you have any? Thanks

    Lets be a bit optimistic here , I'm sure everyone including you here will ace it . Everyone brush up on definitions and mechanisms.

    It was amazing Only things I couldn't remember was the formation of Ethanol with yeast and how Nitrogen Monoxide is formed. I probably dropped a few marks elsewhere but apart from that it was great.
