Study, Comparison

I am 18 and the time has come for me to step out from my childish world. I want to further my studies and become a great dentist. But every time I applied for University, I always compared my trial results with noona's. And this causes my confidence level drops drastically. She got 9A but I only got 3A. Thing like this causes me to think whether I should re-take some papers on SPM June, or go for Form Six. The truth is, I don't want any of those. I want to score my SPM with flying colours and went to the University studying what I like! 

Ya Allah, bantulah hambamu ini! Berilah keputusan yang cemerlang buatku!
