It won't officially be out until after the one in summer.

So, how badly did everyone do the first time?

What matters is I will get an A or 54+/60 next time round. Come at me exam.

Haha Got the right attitude I see :biggrin:

My downfall last time was not reading the whole paper. I missed out on 25 - 30 marks because of that.

Not this time though, that exam won't know what hit it :P

Err go to the Unit 4 January Thread for tips etc.

I didn't do to well But this time I'm going in for the kill, I'm broken the Exam Down into 3 Parts.

1. Definitions around 10% of the marks
2. Equations with Synoptic Questions (Around 65% of the Marks, you need to be able to see where Topics overlap and use Unit 1 and 2 Equations when needed)
3. Essays, and Practicals / EXPLAIN type of questions (Around 25% of the Marks)

53+/60 is around 90UMS.
1. So this time Definitions won't be hard to learn, you can derive most of them from the equations
2. I am going to do ALL the Exam Style and Practice questions from the book - TIMED (I am doing it for Unit 5 right now, and its really a great method, credit to all the students on here, and making notes of the Overlap for Synoptic Questions)
3. Essays and Practicals - I can't do this alone, so I will let my Teacher Mark all my Past Paper questions with Essays, or check the January Forum again to see if there are any notes.

Beast, any study advice would be good bro!

Thanks so much you are a God.

There is always a huge question in g484 papers where you have to come up with an experiment. HOW DO WE DO THIS??? It always gets me low marks :frown:

In short, learn the experiment and it's method. They're usually things like how would you find this shc of water etc etc, they are 4/5 marks that are very easy to lose if you don't learn them

Where can you learn them from, if I had gotten the Questions correct on Practicals I would have got an A, but I did much much worse.

Because the practicals aren't in the book?

If find them really challenging, but will do whatever it takes to learn how to answer them

Past papers, text books etc.. If you look through they do pop up often, use the mark scheme and "build" a model answer that you memorise

Perfect thanks so much mate. You have literally saved me from getting a bad grade in Physics.

I'll do all the Questions - Hand them to my Teacher.

Then Copy and Paste The Essay Style Answers into one word document for Phys 4 and 5, which I will memorize/understand and then read before I go into the exam aswell.

Is there a list of the experiments we need to know (the big 4/5/6 mark questions?)
Also- can anyone explain jan12 question 2cii?

F = 0.25N

W = Fd P = W/t P=Fd/t

d = A = 1.8mm

1/f = T T = 1/2.4x10³ = 4.17x10^-4s

BUT to get from equilibrium position it is T/4 = 4.17x10^-4s/4 = 1.04x10^-4s

P = (0.25*1.8x10^-3)/1.04x10^-4 = 4.32W

Just mention everything:

Equipment used.
Measurements taken.
Calculations made.
How conclusion is formed.
Limitations/errors.

I'll be taking this exam for the first time, I haven't actually started revision yet :| I'm retaking G485 so I'm concentrating on that. I did two mocks at school and got A* in both but that was over a month ago so I really need a massive recap -_- urgh. I bet I'll do worse in the exam than in the mocks.
