    my school sprung most of our ISAs on us the day we were doing them. i walked into the classroom at least 3 times to be told i was doing my coursework there and then. not fun.
    Ouch, that's horrible! We always got given an extremely throrough run-through (it was practically the same experiment and same questions answered for us but with different substances lol).

    How did you do in them?

    in biology our teachers warned us like a week before, in chem it was literally like OW **** -.- when walking in the classroom to see equipment laid out, considering most schools prepare their students and most probably tell them what its on its not fair on the rest of us

    i loved the revision guide you can get 90% with them, this year i used the fat book because there wasnt so much waffle.

    doing the specimen should be enough for bio.

    btw you prob do this, but if you wanna practice for chem from the revision guide, learn from the revision guide them practice on exam questions form the fat book (btw what grades do you need if you dont mind me asking)
    Yeah, ive done lots of past paper questions for Chem, it seems to be most of the right answers. I need AAB (no offer, but reapplying for dentistry). This summer in my exams i need 63/100 marks in computing for the B, need 63/100 marks (92 UMS) for biology for an A. Need 70% to be SURE for chemistry, as my teacher wont give us our coursework score (she said i was A/B so thats around 36/45...or 72 UMS approx) to get an A for chem. you?

    I really think ISA grade boundaries will be lower compared to last year.

    I probably should know this, but what will our paper be like synoptic wise?
    I know some boards do a synoptic essay question, but will ours be 'synoptic elements' sort of scattered through the exam, or will there be a question where it's like BAAAAM synoptic?

    Very articulate question, I know

    Because they both are copies of the chromosome?

    I think it's because somatic cells divide by mitosis (growth and repair from AS) and mitosis produces genetically identical cells.

    I think.
    lol I'm doing great :yep:

    I mean sister chromatids as in 2 of them joined at the centromere, theres one chromatid on one side and one on the other of the centromere, how are they identical when theyve got different genes on them?

    im looking at meiosis btw, at prophase1 when crossing over happens

    Question - for neuromuscular junctions, the neurotransmitter acetylcholine (ACh) is broken down by AChE....

    ... Acetylcholinesterase?

    Or did I just make that up?

    they'll dress up something from A2 with AS stuff for example, they might ask you to compare chromosome numbers in stages of meiosis and mitosis and then go on to ask about the process of meiosis
