OCR 21st Century Biology - B7 and Ideas in Context

Youll get the 1 mark for written communication for sure

haha. That'll get me A*
i counted 41/55 possible marks xD

I'd like to pull your attention to the CGP book content which I SCANNED onto my computer which took about an hour and a half out of my revision time to give a resource to anyone who needed it, so therefore it isn't "unfair",but it's you not looking through the posts carefully and making assumptions on things that aren't true.

Also, I don't want to sound like a pessimist, but OCR aren't going to treat triple scientists who are doing higher tier doing further biology dumb.. They're going to expect a lot more so assuming that because it's just GCSE's that they won't require things, you really need to look back at previous mark schemes with OCR's obsession with essential one worded mark strict answers. This may be disliked but it's the harsh truth.

Will i get any marks for the 3rd question from the back. The one how and where the substances are passed from the blood to the cells.

(I was thinking for the word tissue fluid but couldnt think of it in the exam. I was like BITCH PLEASE!)
So i didnt want to blank it so said. The substances are diffused into the cells through the capillaries. They are one cell thick and connect the arteries and veins.

ROFL. Anymarks for written communication as it is 3+1??

My predicted mark scheme for this question
1 mark for stating that it the blood comes from the arteries to to the capillaries

1 mark for stating the features which enable oxygen to pass into tissues, either capillaries

Now, you've not said anything about how blood gets to the capillaries in the first place so I wouldn't give you the mark, but who knows what the actual mark scheme says, something like oxygen transported by the blood from the heart via an artery would of done the trick

However, you would of got the 2nd mark for describing the wall being 1 cell thin so 2 marks out of 3 overall ;D

And 1 mark for communication
so 3 out of 4?

i wrote the blood enters the one cell thick capillary bed from the artery at high pressure. Water and other substances such as oxygen get forced into the capillaries and surrounds the tissues. It forms tissue fluid. Molecules such as oxygen and glucose then difuse into the tissue.

How many marks?

3 marks..

It seems fun, but my friend just said its all about rivers and is really boring so im not sure
And cause my friend said that different regions do it at different times, like im in London so i do it at a different time to some one in the north, but i dont think thats true :P

This was my last exam SO nervous for results day now!

cheers,

Just wondering where would've the 4th mark come from?

Yeah, some bits are as boring as hell

Andddd ohhhhh yeah some exam boards do it at different times, so basically someone would be sitting the same exam as other students from the same exam boards (but different schools) and they can do it like 2 hours within each other, if u know what i mean???????

And yeah it depepnds what exam board it is, coz some exams actually have the time and stuff on it dont they

Yeah i'm from london too :P

yea yea i get you, i think what he meant was with exam boards like edexcel because they do exams abroad etc, but i dont think OCR do, so i think thats what it is

And where abouts from London are you, South, North, East etc ?

+ Did you have your Geography Exam today?

Yeah, that probs explains why on tsr you're not allowed to discuss the exam until 12 hours after the exam was sat (edexcel)

East & North London I live in Hackney
What about you??

And nope, i resat mine in January, so i didnt have to sit it today, THANK GOD

Check your private messages :P

I used to do that, and don't worry I've just left it last minute so I obviously don't have enough time to memorise the ocr textbook. I know other people that are and I think it guarantees your A* because you're learning from the book the examining body have given. Btw thank you for the resources you posted earlier they're really helpful

isnt it!! I always manage to come out of exams proud of myself but i always manage to get a C
Yeah Bio will defo be the hardest one to come , c

yeeee I fooked up my biology one aha didn't know anything sadface man
