Edexcel Chemistry unit 4 discussion- 26/01/11

I'm doing it. Are you doing an early entry for it? I feel sorry for you if you are...We haven't even finished Unit 4 yet.

it seems maybe you and me are the only ones on TSR doing this beastly exam
nope, we presumed everyone does the unit 4 exam in jan, and then unit 5 in june. when is your exam gonna be then?
also, we haven't finished out course either, the snow didn't help matters, so basically me and my class are s c r e w e d

I'm actually finding Unit 4 alright, but the exam questions are just bitchy. Doing Unit 4 in June.

ugh you are lucky. you must be a genius! me and my entire class are like 'wtf' doesn't help that we have been taught by like ten different teachers lol. there are just so many topics, you have all the organic shiz, then acids and bases, then rates, then enthalpy/entropy and all the mass spectrometry/chromatography/infrared/nmr.
oh right, so you are doing both unit 4 and unit 5 in june? that is gonna be pretty hardcore.

Organic just comes down to memorisation tbh, I revised like crazy for an end of topic test we had and it's now pretty much seared into my brain. Rates, entropy and equilibrium are easy after loads of practice, haven't done anything on acids and bases yet though. Doing some spectroscopy stuff right now, it is quite mind bending at times.

And yeah, unit 4+5 together is going to be hell. Also have unit 4+5 of Bio in June x_x

i am doing this exam in january, with Unit 4 Bio and Unit 4 Physics

I'm pretty much certain that they are going to throw in a question on Chromatography considering how poorly people did in that question in the June 2010 exam.... (i read the examiners report)

Mabye it would be a good idea to start discussing things we dont really like

I understand entropy/equilibrium and acids and bases but the organic stuff is driving me mental
omg really? you are kinda lucky having so much longer to learn everything but then again you will have ****loads more revision to do in a shorter space of time.
I am doing unit 4 ocr biology in january, and then unit 5 in june. our schools do things very differently
what is your other subject?
I am doing history as well, so I have 4 exams in jan and 3 in june. not tooooo bad.

Revising organic is like chewing rocks...which part are you having trouble with in particular? You can always resit in June if you do badly I'm doing AQA Biology...ugh. My other subject is Art & Design, which is awesome because it means I only have two subjects to revise but the amount of time I've spent on my coursework is just ridiculous. If I spent all that time on a theory based subject, I'd be a ****ing genius at it...

meh well it is more the memorising of it that I am struggling with, I have a memory like a sieve haha especially the acyl chlorides, the little buggers.

no wayyyy, my teacher said in no circumstance would we be able to resit unit 4, she said it would be too much extra work. unit 5 looks quite manageable in comparison I think

ooh lucky you, I am doing history which means coursework too, but that is done now wahoo, and then just one exam in summer. I just wish I hadn't buggered my first year of chemistry up, I really hated it and kinda switched off, hence why I am now on a D (2 marks from a C, I'll have you know haha). what grade are you on?

what are you applying at uni for by the way, if you are applying that is!? please don't say chem, I may have to shoot you

also, about the DNP reaction thing you mentioned below your post to me, I am pretty sure we don't. I have the Edexcel specification and it isn't on there, hence I don't think we are meant to learn it

Unit 5 is probably worse :\
I got a B for AS, I'm resitting unit 1 next week, to try bump it up to an A. I've applied for Pharmacology, already got 4 offers woo! What about you?

Good afternoon fellow chemistry peoples!
I am doing this in January, along with C3, Edexcel biology unit 4 and OCR religious ethics...
But I am finding this unit 4 chemistry really good! Actually much much easier then unit 2, but I can only put that down to better teaching and more revision.
I need an A at A2 for my offer, and I got one mark of the A at AS.... so basically need 241/300 this year to get into uni

BTW what coursework are you guys doing? Are you doing the multiple short coursework or the long extended piece?

No coursework for me, all practical exams which I need to ace! I feel that unit 4 actually has less content for some reason weird I know

No coursework for me, all practical exams which I need to ace! I feel that unit 4 actually has less content for some reason weird I know

Its got ALOT of content...

i guess if we compare it from Unit 2... Unit 4 is just the step up with the calculations added to the Kinetics and Equilibria...




With regards to chromatography ill try and post some of my notes up soon

and the SN1 and SN2 reactions, what about them?
