Chances for computer science?

DS has a 35C (33E, 36M, 34R, 35S), 12 APs (including this year), several summer CS programs (including college credit) but only a 3.6UW, 4.02W (lots of Bs while playing football fresh/soph years–but 4.8 GPA junior year). Class rank is very low as a result–like 37%. I know GPA is the biggest consideration for PSU, but will a good ACT overcome that?
