You’re completely right, with my current SATs those are out of my reach. However, I am taking it again in November, and based on current tests(Barrons,CollegeBoard) im expecting to get in excess of 2200.
To answer your question, my activities include basketball, MUN, table tennis, chess, singing for the school choir, drama and theatre, science exhibitions(yes, I do that even as business student). Of those, basketball, MUN, drama and Science exhibitions are inter school level; rest are intra school.
