Re: AS Edexcel Biology Unit 1 June 12- 14th of May"Mature" first time applicant but not a graduate - I dropped out of school in my GCSE year but am doing GCSEs and A levels as an evening/part time student and applied to start this year. Just redid Biology Unit 1 since I got a low A January last year (102), saw how easy June 2011 was and thought try my luck this year to bump it up a bit. Are you applying this year?

For the question I crossed out beta blockers then talked about anticoagulants....

Re: AS Edexcel Biology Unit 1 June 12- 14th of Mayerrrrrm i think i wrote something about how not all the cells had died so they could respire again.. or maybe im making that up.. i cant remember really :P sorryyy(Original post by shahruk)
Wow I wrote the same thing !!
That gives me some solace thanks ! What did you write for " why the tissue recovers after 20mins if ATP is introduced ? "

Good luck with your application -
Re: AS Edexcel Biology Unit 1 June 12- 14th of MayI wrote that once blood flow is restored, oxygen supply is restored. Oxygen removes lactic acid by oxidising it, bringing ph back to normal levels. Cells that have not died can repire aerobically and start to recover.(Original post by Saleha)

Re: AS Edexcel Biology Unit 1 June 12- 14th of MayThe thing I found with this question is that it's stuff i've learnt from A2 biology Unit 5 (i'm retaking unit 1 to aim for an A overall) No way would I have known how to answer this question if I didn't learn it from unit 5, how do they expect people doing AS to know this stuff when it's not in the AS book :|(Original post by farhanyen)

Re: AS Edexcel Biology Unit 1 June 12- 14th of MayDid you need to talk about the fact that the blood carries glucose, which is needed for the synthesis of ATP (in glycolysis)?(Original post by Panicomg)

Re: AS Edexcel Biology Unit 1 June 12- 14th of Mayi think that question wasn't even difficult. right??? cz its many time repeated in o levels too. what i am really scared of is that edexcel people cuts mark even if its not that wrong. i mean they cut marks for the smallest thing. isnt it?(Original post by oli_G)

Re: AS Edexcel Biology Unit 1 June 12- 14th of Mayby the way what was the question??? i cant remember.(Original post by oli_G)

Re: AS Edexcel Biology Unit 1 June 12- 14th of MayIt only asked about structure, so I don't think you needed to write about functions(Original post by unity93)
omg, for the structure of the heart 5mark question, who related the structure to the function?????? the qu said describe the strucure, so all i did was say oh ''the heart is divided into four chambers..has semi lunar and atrioventricular valves, tough tendinous chords, left vent has thicker muscular wall...blah blah...i didnt actually mention anyhting about the function and how these features actually help the heart do its job. Anyone know what im on about??

Re: AS Edexcel Biology Unit 1 June 12- 14th of MayI don't think they cut marks do they? Didn't seem to say that in any mark schemes...(Original post by shahlakh)

Re: AS Edexcel Biology Unit 1 June 12- 14th of MayI did but for some stupid reason I wrote glycogen instead of glucose... I think glycogen is the store of excess energy created by respiration so guess I won't get the mark. But yes I think both glucose and oxygen are the raw mats for respiration which creates ATP.(Original post by oli_G)

Re: AS Edexcel Biology Unit 1 June 12- 14th of Mayyeah may be u r right. may be they dont. cz they just want answer which is to the point.(Original post by katu_mcd)

Re: AS Edexcel Biology Unit 1 June 12- 14th of Mayi think writing glycogen is correct. cz i read some whwere it is a storage molecule which is stored in liver and muscles. when needed for respiration they can be broken down into glucose which along with oxygen can in turn be used in cellular respiration, which yeah creates ATP. I think u wont loose marks here. cz thats the fact.(Original post by katu_mcd)

Re: AS Edexcel Biology Unit 1 June 12- 14th of MayThe is no way that it asked for the percentage.If you check the front page, no calculator mentioned at the equipment, only a ruler.So it asked for the diameter.(Original post by cspb)
It was asking for a percentage increase!!!!!
I measured it 1.8 cm

Re: AS Edexcel Biology Unit 1 June 12- 14th of MayYep, you're right. I got 1.9cm.(Original post by RioGk)

Re: AS Edexcel Biology Unit 1 June 12- 14th of May
Sorry for the thread revival, but this was my first exam, and one that I complained about quite alot, heck when I unleashed my rant I got 10 likes!
I must admit, with A levels don't entirely trust your instinct, quite a few of my worries were non-existant, infact in some modules that I thought were bad, were actually better than the other one in the subject!
The biggest shock for me is this specific exam, I can't believe I have been somehow awarded 120/120 UMS for it, while the second exam which I thought went much better I got 103! Some very lucky bullsh*tting from me. Still, I'd of preferred to do well in physics, and my bullsh*tting didn't work too well for my first physics exam, got a B in it (A overall though). Need to sort out some retakes, still overall pleased!Last edited by Andy16; 16-08-2012 at 12:46.
