HOW MUCH DO YOU PEOPLE THINK YOU'LL GET?

Hello Everyone,
This thread is for discussion purposes for unit 1 edexcel biology in january..
We can discuss the various sorts of questions/problems which we have :smile:
Good Luck ! :smile:

Hey, I did this paper last Jan and to my surprise, I gained a good grade

Tips:

- read the question properly, I can't emphasis this enough
- pratise drawing diagrams and LABEL even if they don't tell you to
- know your experiments inside out including control v. It could be like 5 marks. In my exam, I was asked to describe the daphnia experiment, very easy 5 marks for me
- know how to interpret and describe graphs/tables; graphs WILL always come up and it's pretty tricky but its easy marks if you get the gist of it
- read your specification to make sure you know everything
- nail thr MCQ; easy marks
Oh and check your paper

Good luck :smile:

I used those 2 books and I'm using both for A2 now
I made revision notes on those books too to supplement my revision, they really helped since it was in my handwriting, quick to the point and easily portable

And your welcome, any help, just PM me :smile:


hi mate

I just wanted to know, when doing the daphnia experiment, apart from the HUGE cost of using an electron microscope, what other reasons are there for using a LIGHT microscope and not an electron microscope?

Helloo people ! :smile:
Hope revisions going good :smile:

I have a feeling that there is going to be a gaseous exchange question in the paper...& i kind of suck at this topic..so would be grateful if someone could help me out..
If someone could
1. give me the list of stuff & explanation which can increase gaseous exchange
2. anything else which you think i should know :smile:

Happy Revision!

can any one give a list of things that are missing in the CGP book but you still need to know it for the exam?
Taking this exam to and i think this year there will be questions on the heart.

Anything that needs to be used under an electron microscope needs to be non-living/dead. They have to be treated with heavy metal ions. For the daphnia experiment you only need to record heartbeats not see anything in great detail.

Hope that helps.

This video is transport of oxygen and carbondioxide, not sure whether it is in spec.

Size of the membrane : gases diffuse faster through thinner membranes than thicker membranes.
Surface area: larger surface area = faster diffusion
Moisture on the surface: Is a factor but I don't know the explanation for it.
I gave this exam in Jan..and the best advice I can give you is that make every second count.

Good luck

I dont think sooo
But im not sure..how about you checking the specification?? (then let me know:tongue:)

If you are looking for topic summaries, I could offer Topic 1, Topic 2, Topic 3, Topic 7 and Topic 8 summaries, based on the Salters-Nuffield Advanced Biology for Edexcel AS and A2 books, published 2008. You can get them at: www.shortstories.ch/bio.html. Good luck to all for your exams :-)
