Day 20 & 21 - trial lab test and lab test

stress..stress..stress..stress..stress.. i was so nervous about the lab test... even though we had a trial lab test on monday... but still, i've got no confidence because to me, it's so hard!!! the trial lab test was so much simpler than our lab test!! >< because i had so much trouble trying to figure out what's wrong with my program... it was almost done you know!! just that last part... i was crazy... because i edited my whole last part of the program... i don't have so much confidence getting those marks... TT what can i do? its over..
