Edexcel 6BIO2 ~ 3rd June 2013 ~ AS Biology

4a) No point doing this im sure many will obtain four marks.

64 for an A? That's a bit high. This was definitely more difficult than Jan '13. I'll say 61.

ALevel96 mynameisntbobk CoolRunner - guys please check for me this answer (3 marks) where it says describe the effect of concentration on mean length of the tube...
here is what i wrote:
-A slight increase in the mean length of tube when concentration increased from 0.0000 to 0.0001 mol dm ^-3
-A decrease from 90 to 28 mm in the mean length of the tube when the concentration increased from 0.0010 to 0.1000 mol dm^-3
-An increase of only 1 mm in the mean length of the tube when concentration increased from 0.0000 to 0.0001 mol dm^-3 i.e a very slight increase .

Thankss in advance

When do you reckon someone will be able to get hold of the paper so we can see it?

mynameisntbobk can they gv 2? for saying abt the decrease?

It depends on how nice your marker is.. I think the fact that you talked about it increasing and decreasing (the change in direction) may be a mark if the examiner is nice

well...in the worst situation am losing about 22 marks ....in the best situation am losing abt 14 marks ...so can hit an A?
wbu hw did it go ? what r u expecting?

Hopefully! good luck for August.

I actually haven't marked my work with the unofficial since I can't remember most of what I did. I think though, I may have lost about 4-12 marks depending on the examiner by looking at it.

thanks! good luck to you too!
so how was ur aqa chemistry? i actually did edexcel, but am hoping for a medium A ...tho chem is my worst subject

Thank you
Chemistry was surprisingly alright, fairly hard exam, so a lot of mistakes made, but hoping I've done enough for that. Oh right, do you think it went well then?

I did a max of 12 mistakes (checking with the unofficial ms ) 6 of them in the mcqs (what a shame ) .....this for edexcel i mean...u did aqa right?
