Today i am having the micro and nano technology common test and i just prepare this common test only 2 days before this day, but luckily my teacher for this module,mr peter lim, is quite good cos he had given us quote a lot of hint and i think i can pass. although during the common test some answer to some qns i cannot remember but i still write sth on it, cos our teacher was there also as a invigilator say cannot leave blank. finally finished but still worried cos more exams are waiting for me, starting to feel stress.
