How bad are straight 4's?

I’m a rising senior applying ED1 to Vassar, and checked my AP Scores today, and out of 9 exams, I got a 3 on Biology, 5 on Macro, World History, Geo, and 4’s on Lang, APUSH, Cal AB, Micro, and US Gov’t. How much of an effect would that have on my chances?

Other academic stuff: Not great (second decile, 3.75 UW, 4.23 W), 1520 SAT
EC’s: 8/10
Recs: 10/10
