My Piano Theory Test

Last Wed, my piano teacher gave me a theory test and i got 83.5/100!! And she said i got an 'A' merits!! She's so proud of me!! actually, my previous test i only got 65 n tat means i fail. But now i pass this test by 18.5 marks!! haha... so happy!! My teacher told me to keep up my good and so better to prove it to my principle tat he is wrong!! As he keep looking down on me and keep saying that i'm a 'slow learner'. And how can a 'slow learner' learn? And last year i got back my practical exam paper, he was shock when he saw my result!! His eyes nearly popped out!! LOL!! coz i get merit!! He can't believe it!! coz my Grade 1 result is not that good. So this time, i must let him faint whne he sees my theory test result!! Faint coz i passed it!! But in order to get good results, i have to keep memories those sharps and flats. Like b major had how many keys n things like that.. And also those stupid italian, latin, french and german language. It's so difficult!! So now for me is stress+hardworking+blurr=crazy!!! So pls pray for me that i can defeat all those difficult sums and that stupid principle!! heez
