SAT 1 Or SAT Subject Test

<p>I'm planning to apply to NUS (National University of Singapore) for engineering.
I am from India (CBSE), class 10 CGPA- 9.6 . Currently I'm in 12th grade.</p>

<p>SAT 1 score - 2020 -CR 600 M 720 W 700
NUS says that it does not require SAT scores for CBSE applicants, but still I guess it gives you an edge over the others if you've got good scores.</p>

<p>So should I give the SAT 2 in October or just give SAT 1 once more and try for a better score?</p>
