<p>Here's how the grading system in Singapore O Levels works: A1,A2,B3,B4,C5,C6,D7,E8,F9</p>
<p>Ive gotten 5 B3s, 1 A2 and 1 C6 for my O Levels (GCSE equivalent)</p>
<p>Although I am taking A Levels next year, I've come to realise that O Levels results also play an important part in the application process. Do you think its a good idea to resit my O Levels ? Will the universities mind that I originally took my O Levels in 2007 and that i retook it in the year 2009? Or should i just forget about retaking my O Levels.. But surely it would affect my chances at a top US uni? :(</p>
