OBC Prac and TKD!!!

almost screwed up my OBC prac test aHHH!!! PHEW!!! Seems to be shou mang jiao luan(busy hands and legs) everytime i had a practical test. PANIC-ed! Tried all the test and all seems to give me negative results, pek cheked + stressing from the prac lecturer... cant take it! I even spilled like 3/4 of my chemical, but luckily, still have more than enough for me to do my tests. Luckily, when i handed in my papers, my lecter said that i am on the right track... *PHEWWWW~!*
