Past papers are useless this year. Atleast 75% of the questions for Bio and Chem have been language based. :mad:
i hate AQA

You can use them for other things such as managing time which is usually the issue. Also, you can practise the calculation based questions within the paper which help

I think it'll probably be on the life cycle of stars :afraid:

Anyway, what do we need to revise?!

Sorry, I meant for unit 3 forget to put that :/ I sat unit 2 last year because I did core in year 9, additional in year 10 and now further additional in year 11... I have no idea what the six marker could be :/

physics is definitely my weakest of the three sciences. honestly terrified for physics 2 and 3 i'm less worried but still scared for (i think it's a trend with me and the exams right now i've been finding the unit 3 exams much better than the unit 2s)
hoping life cycle of a star comes up as a 6 marker on unit 2 because i actually understand that
and unit 3 i'm predicting transformers

I think there will be a lot on electricity on P2, the 2014 paper had very little on it.

There usually is quite a lot on electricity as the topic covers two chapters..
Luckily for me it's my strongest bit along with forces

with the Biology and Chemistry 2 & 3 units this year the 6 markers have tended to be describing an experiment or based on some information they give you which i absolutely HATE so I'm praying that something nice like "How do transformers work?" will come up. Unlikely though...

As far as i can tell there's never been a lot of P2.3 work and momentum topic so maybe they will do a 6 marker on how to find the weight of a beam? I wouldn't mind that.

For P3 i think a 6 marker about the eye and similarities/differences between the eye and a camera could be the one. Maybe that's just wishful thinking...

If it's on life cycle of stars I'll have a scram inside, I'd be so happy!

My physics teacher is predicting that Hooke's law will come up if that's any help:getmecoat:

hmm I think I did quite good in the 6 markers for c2+3 (Cant say the same for biology), but I found the 1/2 markers harder in chem? wbu?

Hi

Here is a MyGcseScience video describing Nuclear Decay Equations.

If an alpha particle (2neutrons and 2 protons) is emitted the mass number goes down by 4 and the atomic number goes down by 2. If beta radiation is emitted the mass number stays the same and the atomic number increases by 1 as a neutron turns into a proton and an electron is created too. Forgive me if this is incorrect.
