cos im extremely bothered by the practical exam today, i mean yest cos it's officially tues right now. it's gone case for my practical exam. anw i actually got a conical flask that leaked. how suay can i get, out of all the 50 odd people in the lab, i have to get one that leaked?! ok lar it's my fault cos i didnt inspect each and every single apparatus carefully for leaks and cracks, but then again who would right? i thought the apparatus were supposed to be brand new (like last sem), or at least crack-free. 15 mins passed, i realised that my bench kept getting wet, my stopper flew out of the flask?! i picked up the flask and saw that there was this crack at the bottom. and my flask was leaking........... OH MY GOD! OH MY FREAKING GOD!!!! i was so scared i quickly dashed to the lecturer and asked for a new flask. by then it was too late, it leaked out quite a fair amount, but it was still enough to last me throughout all the titrations. and i didnt want to redo, cos i was already one of the slower, erm probably the last one, in the lab. sigh. should have redo you know. i asked the lecturer after the exam whether the leaking flask will affect my results, he said it might to a certain extent. :( whatever lar, i got some parts of the experiment wrong already. and it supposed to be an easy paper. oh and i couldnt do a very simple mechanism. cos i just couldnt think. what the ___________ is wrong with me?!?! how STUPID can i get?!?!? im just pissed cos it's like bad luck kept following me throughout this entire lab module. for instance, printer died (for no apparent reasons) when my group wanted to print out the data sheet. instrument went completely nuts and we had to redo the expt again and again and again. booked the experiment and ended up TA didnt allow us to do and thus wasted my time preparing the lab report the night before. lab quiz asking for definitions for some crazy computational terms. TA telling us wrong stuff. strict markings for lab reports. and the list goes on... ok im done ranting. 12 more days to first paper. and im too demoralised to start studying. |
