Hi All
I thought it would be useful to have a thread in which we can all discuss the 2017 Science exams. We can help each other with areas of weaknesses, as well as discuss how we are feeling about the exam, etc.
Also, if you have any useful resources or predictions to share, please do as it will benefit others. If you need any resources, just ask and hopefully someone will be able to send them.
All the best with revision and the exams!
Revision List of Topics:
B4
Features of all living things (chemical reactions in cells - respiration, photosynthesis - and cell structure)

Stem cells will almost inevitably come up. Usually appearing in B123, OCR chose not to include them in this year's core biology paper so a question should appear for B5 in this year's additional biology paper.

Why? It is probably o e of the easiest 6 markers because you dont have to really talk about anythibg specific. Meiosis and mitosis are annoying because theres so much to talk about and I dont like writing essays 😂😂

Probably will be phototropism which is nice bc not much to say - I think something about meiosis and meiosis came up last year so we might be lucky and not get it! If anyone has the paper please share what was on it!

Sorry, I do not have those. I am still trying to get hold of those, so if I do I will post them.

Am just saying this because I was messaged yesterday since I asked for Mock set 2 in maths which "goes against the TSR rules"

Hi, could you please make a list of topics for each module like you did for p456 please? That really helped with revision and planning 6 mark answers.

Thank you, I appreciate it. I meant to ask my teacher (who has access to the Interchange) on Friday, but unfortunately forgot.
