<p>Would my chances of getting into an ivy league decrease if i did not do exceptionally good on SAT subject tests but still did great on SAT/ACT</p>
<p>Of course your chances would decrease. Now does it disqualify you? Hardly, but your class rank will need to compensate. If your school doesn’t rank, your other test scores (ACT/SAT/AP) become much much more important. Nothing would be guaranteed. Ideally, everything is good.</p>
