B7 21C (21st Century New GCSE Biology - UNOFFICIAL MARKSCHEME

Scroll to see replies

I hope so. It was such a bad paper - nothing on the skeletal system, blood, tissue fluid or eutrophication - more on flipping risk and LCAs which, I thought we only had to know about for C3?? Do they know that was over a month ago?

Glad you found it better. I'm sure you'll get a good grade :smile:

Lo l just crossed a tweet from you on the ocrbiology page. Yeah i also found the paper a little hard. There was too much analyses and the paper focused too much on geography and had Chemistry in it omg. I'd be so sad if i dont get my A* in results day

Biology is the most dull science imo, but using other full subjects like geography and chemistry won't liven it up!! Haha
You stalking me? Haha jk
And yeah there really was. Why can't a science paper just test us on our knowledge of science for once? Like would it really be so hard?
Same really as I know I'm capable. But it wouldn't surprise me.

I don't think the grade boundary will be any higher than last year because there were quite a few awkward questions.

Yeah same; in class im pretty much an A* student but these irrelevant OCR exams always trip me up. I done super well in all my exams but i think i scraped an A in B7 so i proabably lost my A*. :frown:

I was raging, I could've written an essay on eutrophication I know it that well. And diabetes. I was so annoyed none of them came up 😒

Since we started doing GCSE science I've pretty much struggled. I was flying before then, before OCR screwed my life over!! And I doubt you have, B7 is only 25% so if you've got 75% A* then an A in B7 isn't going to change that :smile:

Blessing you know that the percentage increase is like 105% cos it is is like 5 to 11, so it doubles

I thought it was how much the percentage risk increased by and wasn't it in percentages to begin with?? :confused:

No as that was the unit for the vertical axis and then cancels - it was like 10 - 5 / 5 ( i can't remember the exact numbers) and then multiply by 100. It was percentage increase

Can you include the marks if possible?? Thanks :smile:

Will see what I can remember. Bare in mind these questions aren't in order.

It was an INCREDIBLY poorly worded question, OCR at their finest here.
It didn't want percentage increase, it wanted increase in percentage risk.
A very easy mistake to make though.

No, I don't know how many marks the questions were worth really. I will try though.

15. Ecoservices for humans include (you only need three for three marks)
pollination
clean water
air
fertile soil for growing crops
food e.g fish and game

Could you have put plants are used for medicine,wood is used for furniture and paper?

wood was already in the question i believe but i think plants for medicine would be accepted. x
