Right, its getting on my nerves now.
I have a maths exam at Uni @ 9:30 in to morning that is a resit of one i took in the summer. I failed it in the summer by 2%, which really pissed me off.
If i fail this exam Im still able to continue the course next year, although it apparenlly makes it harder for me to get a better overall mark come the end of my degree, even though the first years results dont contribute towards your final mark, and i dont do this module next year.
Anyway, i started my revision for it yesterday, and have done a grand total of about 45mins revision including todays efforts  .
Anyone got any ideas on making me convince myself to do some revision, appart form looking like a dickhead by walking out the 3 hour exam after about an hour cause i cant do anymore? .

I find writing things over and over again means I take it in...also test yourself with a mate as that gets u starting to think of thinks from memory and helps u once your on there....

Would have done the "test yourself with mates" thing, but most of the people i hang about with on the course dont do that module, so im on my own . I wouldnt mind but it was a shit module anyway. The bloke hadnt a clue what he was doing, and the whole organisation of it all was a joke!
Also i flunked the coursework as he didnt go into depth on the principles behind it, but then continued to also base a large part of the exam on the same topic as the coursework!?! .

Its pretty much that, .
Its a module called moddelling concepts and tools. Basically its a combination of all the alevel sylabus' so that everyones on the same level. Its goes into a bit more detail though by applying some of the theorys to actuall problems.
Heres what my Coursework problem was if you can make sence of it...
quote:
Two tanks are arranged in a cascade i.e. the only inflow to the tanks is into the first tank, the outflow from the first tank flows into the second, and the only outflow from the cascade is from the second tank. Each tank is always full and has volume V m3. Both are initially full of brine of concentration c0 kgm-3. A flow of R m3h-1 of pure water is fed to the first tank.
(i) Develop an equation relating the concentration of salt in the outflow of the second tank
(y kgm-3) to the time (t h) that pure water has been fed to the cascade. Include the full modelling method in your solution. (50%)
(ii) Write a short MATLAB program, which inputs values of V, R, c0, and tmax, where tmax is the longest time you wish to consider, and calculates y for t from 0 to tmax. Plot y against t. Include the program, sample output of it running, and the plot in your solution. (20%)
(iii) Expressing your answer in terms of V only, derive an expression for the volume of pure water that must be fed through the system in order to reduce the concentration in the second tank to c0/100 kgm-3. This should require the numerical determination of the root of a simple equation. Use an Excel spreadsheet for this purpose, copy your worksheet into your solution, and briefly describe the method in your answer. (20%)

Its not the matlab part that i hated as im not too bad with that, and blagged the help of others in the group to help me complete it  .
Coursework was handed in in May and i got about 20-odd percent for it  .
Its just i cant really understand the concepts of deriving the equations for the concentration/time/volume aspects due to him not teaching them adiquatly enough (IMO), so im pretty much buggered .

Iv'e got a Hoofing Engineering Mathematics text book, but thats just a hoofing big book by Stroud .
'Tis quite a good book and explains things in detail well, just not stuff that i need like the above question .
