Grieve! haiz...

Today was my violin exam. I prepared it for 3 months ago...I went to the exam venue-City Bayview Hotel during afternoon. The receptionist told me that I am the next candidate..Omg..I haven warm up yet li...summore my piano accompanist get sick and came late...
Luckily the examiner was very kind, she told me about her Christmas caroling stories in UK, and I also tell her my caroling story in college..she keep praising me non stop and make me bashful!!! After my accompanist came there, I started my 3 pieces...OMG..It was intolerable, I played it unpleasantly and very "gili", because I was nervous in the exam room and my hand keep shaking...I really wanna cry out in that time....but the examiner still say "great!!enjoy your music man!!"...shit lah!!! the pitch like dinosaur also called great!!! I already dishearten during that moment..Follow by the technical work and studies..I think I done OK in this section, but still abit nervous and not so perfect than I aspected. Well, the last part of the exam is the sight reading and aural test..I'm surprise that I done it well especially sight reading...haha..but it just cover 20 marks...
haiz..I think I cant score distinction in this time le....If the time can re-gyrate, I think I will done better than just now....sad!!!! Why I am so nervous??? How to avoid it!!??!!! T.T
