Reading a course in arithmetic by Serre is going to get you nowhere. For starters, you're extremely underprepared. The other guy is trolling you. Secondly, there's plenty of interesting stuff at the precalculus level. You should concentrate on dealing with the fundamentals first, even if it's boring. If you don't know precalculus well, there is very little you can do.

However, this doesn't mean you can't look into things that should still be at your level of understanding. I think one of the more interesting things you can look into is baby-tier analytical geometry. Stuff dealing with conics and low degree polynomials, or perhaps lines and circles stuff.

>Geometry: A Comprehensive Course (Dover Books on Mathematics) by Dan Pedoe
looks nice
>Geometry of Conics (Mathematical World) by A. V. Akopyan, A. A. Zaslavsky
also looks nice
