Applying for NUS (Requirements)

<p>I'm a student studying in India in an ICSE board school.
My 10th board mark is 94.4% and I've just started school for 11th.
Does NUS (National university of Singapore) consider my 10th board marks too when I apply?
And if I take SAT, SAT2 and AP subjects, will it help me or am I just wasting my time?
Also, how much do I have to get in 12th to get admission in NUS for sure?</p>

<p>One more thing. What kinds of extracurricular activities do I need?</p>
