    Is anyone taking OCR Biology with the unit "Biology Foundation"
    has anyone got any tips on how to revise for the molecular structures for the biochemistry sections. i am finding the revision quite hard to remember, especially when the exam board tends to set essay questions.
    any tips wanted as there is an exam on Monday!!!!!!!!!!!!!!!!!!

    thanks

    The exam is on Tuesday . When i first started AS Biology i couldn't get my head around that section at all. We did that one first so i was like "woahh, this is hard" but i found that just by going over and over it it sunk in. I'm so glad i did Foundation module in January and did well on it! Are you doing HH&D and Transport as well?

    Just write out the structures over and over again. Then test yourself on them. I assume you're referring to amino acids, phospholioids?

    Basically learn the diff bonds glycosidic etc
    Learn the functions
    Learn examples of each one
    Learn about Hb
    I bet you actually know alot already and are stressed a bit.
    MAKE SURE YOU KNOW HOW TO TEST FOR EACH ONE (INC REDUCING AND NON REDUCING) thats always been a favourite
    And reactions eg condensation hydrolysis and show how to 2 mono 's make a di
    Learn every single thing to do with cellulose.

    this may help if you're really stuck http://www.biologymad.com/but if you've got the OCR Cambrdige Biology 1 book- use that- it tells you everything.

    just keep reading and looking at diagrams until it sinks in.

    But a few things off the old spec are in there that you don't need to know and a few things from the updated spec since 2002 are missing

    The bio 1 book (2003 copy) is basically all I learn through, so if it isn't in that, I won't know about it (bar some obscure plant bits which were taught to us to make me loath plants even more)

    Is there anything not in the book which we need?

    Good luck to you Sarky!

    I'm leaving my revision until Sunday - it gives me two days - since I've already been revising. I'm glad I'm not doing foundation again....I may end up doing it again next January if I don't hit the grades I want though.
