I always keep a pack of pro plus just in case of emergencies, and last night it really payed out. I realised at about 6pm as I checked the printout of a piece of coursework due in today, that I had made an error in my calculations right at the start It meant that whilst correct in general, aaaaaaall the resulting tables and graphs were off by this small calculation error. I was up until 5am sorting everything out and a couple of the little pills kept me going. PHEW!! Its a habit I picked up from my father, who always has a packet in the car and at home etc just in case something crops up which requires him to be awake much longer than he should be. So thanks dad, you saved my coursework!!
