But how you know the pros and cons? They are not on the Chemical Ideas book and on the the chemical storyline book there is a lack of detail.

i know them cos of GCSE chem, tbh they are more likely to ask you about the pros and cons of hydrogen, LPG or diesel which are in the specification and the storylines.

See the past paper questions of fuels and their pros and cons. Their mark schemes are very concise and annoying.

aren't they always, bugs the hell out of eveybody , what i tend to do is get worried that i haven't written the key word and so i start writing everything i know about the topic in the hope that something i've written will get me the marks i desperately need but then you get a load of timing issues :angry:

i've resorted to learning mark schemes now

yeah, with the long questions on shapes of molecules I do a similar thing. I say "regions of electron density repel as far apart as possible" first so I don't forget. Then I say how many regions there are...

3rd time of retaking this paper, I just can't seem to get above 90% for this paper. It's frustrating.

This is my third time, I absolutely cannot stand this paper. I'm aiming for an A* overall, so getting 90% in this paper is a must.

Does anyone know how picky the examiners are with the mark scheme? For example, I always say groups (note- not pairs, GROUPS!) of electrons rather than electron density. Some mark schemes say allow it, others don't mention it at all. I've never seen one specifically disallow it. I'm aiming for over 90% as well, so I can't really afford to drop stupid marks like this :L

they are ridiculously picky to the extent that it's a piss take, did a paper and was asked about what spectra produced coloured lines on black background, i wrote emission spectra they didn't accept it, the answer was atomic emission spectra! just goes to prove that the difference between an A and a B could be 1 silly little mistake like that, puts a lot of pressure on a person :/

You do know that AS percentage does not count towards an A* you just have to have got A's and then get 90% in the A2 exams gets you an A*

:O
is that 80% as an average over all the AS course? Cos I sort of messed up the coursework.... I should be able to do better on the retake but it would be nice to have some excess marks to fall back on.
