    ******************************** ****[AQA BIOLOGY UNIT 1 EXAM 2015 5TH JUNE]******************************** ****

    Hey guys,

    First of all, I just want to say good luck for tomorrow and get revising if you haven't !
    I would personally advise revising Auxin a lot.

    However, this is the official general exam thread where you can post ANYTHING at all in regards to Biology Unit 1 (B1 AQA)

    Good luck once again

    Predictions of ANY kind would be appreciated (Topics, 6 Markers, Types of questions)

    From reviewing past papers, I think the exam will be based on reviewing investigations rather than observing data.

    i really should be worried about this exam since i've only started revising for it this afternoon, but i'm not worried that much since i've got an afternoon to revise before the exam tomorrow
    after doing b3, b1 seems like a breeze

    my teachers did some question spotting for me and they said these are VERY likely to come up:

    -the carbon cycle
    -the menstrual cycle / ivf / the contraceptive pill (maybe even embryo transplant or adult cell cloning)
    -preparing uncontaminated cultures - THIS MAY BE THE 6 MARK QUESTION
    -indicator species (lichens ect)

    they also mentioned tissue culture and cuttings, however they said it wasn't as likely to come up as the others.

    btw, i would recommend watching 'freesciencelessons' on youtube (https://www.youtube.com/channel/UCqb...BVG3_bw/videos) , he condenses topics into 3 minute videos and I find him far better than mygcsescience

    I think the 6 MARK QUESTION could be on preparing uncontaminated culture mediums too! I just need to whiz through IVF and embryo screening and menstrual cycle but they are all pretty simple. We have also got until 12.15 tomorrow to revise!!! GOOD LUCK EVERYONE WHO IS SITTING THIS EXAM X

    how do you actually need to know about that though. I really dont think there is much to say about them apart from:

    lichen=sulfur dioxide (air pollution/quality)
    invertebrate=water quality/pollution

    You don't need to know about certain ones, only what they indicate. (From Science Teacher)
