As nige says , but leave out the wine. There was once a bunch of tiffies who were nicknamed the "art scientists", they failed everything from day 1 even their top students were returning scores of 40% to pass.
Nearly all did pass eventually but it was down to a math buff on the course who was also a good teacher, knocked spots off the dropouts in the Kremlin.
Is the smiling assassin still there?
Sometimes, just sometimes you get a straight answer on here.
Get yourself on to www.freestudy.co.uk the site can be busy but it has loads of tutorials there and it may just help sink something in.
Plus you can take it home with you. Something you probably wouldnt wanna do with some of the Maths tutors there eh! 'Shudder' Nice Bratties in the morning tho' ha ha
This is a good site for any Tiffy wannabees BTW Maths Science the lot.
