OCR Chemistry B F331 Chemistry for Life (13-01-2012)

F.Maths I would talk about the test cause talking maths hidden in a chemistry discussion is genius. But I already got 10 warming points yesterday so can't risk it

All I'm going to say is that I died in my C1 exam and i'm preparing myself for a retake- i've always been terrible at maths I don't know why the hell I took it to as level.

Most people who took just a level maths found it difficult but I couldn't tell how difficult because I was sitting c1 and c2 with a few others we couldnt talk to anyone because some people in my school retakers had their c2 when I had my c1. So I could only talk to others in f.maths but they found it a bit difficult. And in c2 the kid next to me gave up within 15mins if the test, he slammed his head in the table closed the paper and gave up. So c2 was also a bit more difficult than usual

Would everyone agree that the F331 Exam today was based more on Elements of life rather then fuels?

If i remember correctly that 3 questions started as elements of lifes then one talked about fuels aswell

it's not fair, i'm so embarrassed to face my maths teacher, he had so many hopes pinned up. I'm so worried, their is definitely a negative momentum that is going to build up. I'm not a natural at maths, no matter how much hard work I put in when ever I open a maths paper I run out of time then panic or freeze. :/

... Friday ... The.... 13th....

That's Also partly worried about not getting A's in maths and physics because if anyone needs help they usually turn to me or one other who is a bit better than me. Don't wanna let them or my teachers down (high expectations/too much pressure)

I doubt it will ever be that high. 51/60 at best, unless OCR are just sadistic. I don't think it will be higher than 50.

exam boards did this purposely, they are really cow and half.

Nothing to do with chemistry just to get attention.
Anyways, few questions, how hard is m2? How much of a step up is m1 to m2?
And is it possible to learn m2 to 2months?
By the way I won't have learnt C3 or C4 at this time will just be learning it
Thanks

M2 is very easy. It took me about 2 weeks to do from the textbook doing a few hours each day.

You can do M2 without C3/C4, but some of the trig identities from C3 could help for the projectile motion topics. In M2, you have

Projectile motion (if you do AS physics you'll be fine with this)

Particle collisions (instead of 2, you have 3-particle collisions and ones that hit a wall, bounce back, so you have to account for several collisions occurring, and Newton's Law of Elasticity for collisions is used (v = eu))

Lots of centres of mass (of a wire framework, of a lamina, of weird shapes with holes in them, and determining whether or not these objects topple when put at a certain angle on an inclined plane, etc.)...

Using calculus to find displacement, velocity and acceleration

Work, energy and power (again, similar to AS physics but there is quite a bit more in there)

Statistics of rigid bodies (more moments, but this time you have things like ladders resting against walls where you have two co-efficients of friction, and two frictional forces with two normal contact forces). Very similar to M1 but a bit trickier because you're required to find the perpendicular distance for pretty much any question.

It's a bit of a step up from M1 (it's harder), but it's more fun in my opinion.

Cheers, thanks for the detailed notes, I will probably start learning it this weekend or next weekend. I'm doing as physics at the moment and I'm strong with horizontal & vertical velocity in physics (was gutted it didn't come up).

As out of interest does your school teach concept or content for physics? Assuming your doing edexcel salters

Both... we have finished Mechanics, Waves, DC Electricity, Nature of Light, and have just started Materials and will be doing the coursework next week. It's a boring course.

Alos gutted cause i forgot the 2- on sulfur ion. i forgot why i put it in bracket in the first place, i will get 2/3 for that. Starting to think i just missed out on an A
