Yup
I don't think the chemistry is that hard, it's just exam technique, and the boundaries are usually really tight :s-smilie:

I need to smash this exam to make up for my coursework... Does anyone else feel that Salters Coursework must have spawned from the very depths of hell?

Not something I would recommend :P

I've only really made notes, haven't properly started memorising the content :s-smilie:

And I got a B in F331 and F333, and failed everything else, hence all the retakes :/

What about you?

This is going to be one of my toughest exams :frown:

I got a high D for Unit 1 in january.. Hoping to get at least a B or A in Unit 1, I really want to get a B in this exam!
Any tips on how to revise? I've written all my notes and just going over the content again.
Hopefully I get a B overall in august but I really want an A like all of us do i guess! :smile:

I would say make sure you understand the content so you can apply it to different situations. And also do loads of past papers :smile:

So i'm currently revising atmosphere and i was doing the assignments in the storylines and am totally stuck on Assignment 11! can somebody help me please! i'll post the question as well :smile:

'In 2001, the concentration of CO2 in the atmosphere at Mauna Loa was 370ppm(by volume). The total mass of CO2 in the atmosphere was estimated to be about 2760Gt at that tim (1 Gt= 1 gigatonne = 1 x 10^9 tonnes.)
Through the 4 years from 2001 to the end of 2004, it is estimated that 34Gt of fossil fuels were burned throughout the world.
In 2004 the measured % of CO2 in the atmosphere at Mauna Loa was found to be 377ppm (by volume).

Now answer the following questions:
a Assume that the 34Gt of fossil fuels burned in the four years were all C. Calculate the mass of CO2 formed by burning this mass of fuel.
b Calculate the new total mass of CO2 in the atmosphere at the end of 2004, assuming that the extra CO2 came only from burning fossil fuels and that it stayed in the atmosphere.
c By what % would you expect the concentration of CO2 in the atmosphere to have increased in the 4 years?
d By what % did the concentration of CO2 in the atmosphere actually increase in the 4 years?
