Im 17 and my iq 128 is that good?

Let me guess, you clicked on one of those banner ads that said "Miley Cyrus's IQ is 125, what is yours?"

The information gleaned from banner advertisers is worse than useless, and you've given no information to demonstrate any significant level of intelligence. Come back in a few months and tell us what books you've read and what you've learned from them, and what colleges you've gotten into, that could be more worthy of praise.
