<p>Colleges have few apps who get 800 on math and 500s on verbal, so there isn’t a large enough reporting sample size to estimate how much it hurts your chances with much accuracy. When I applied to colleges several years ago, I was in a similar situation. I scored 800s on math and math II and near 800 on math II science (don’t recall exact scores), but only 500 on verbal. The low score did not prevent me from being accepted at highly selective schools. Instead I was accepted at Stanford, MIT, Brown, and Cornell. I expect that the accepting colleges gave the math and science scores more weight than verbal because I was a prospective engineering major, treating me as a specialist who excels in his desired field, rather than a well-balanced app who is pretty good at everything. You can form a well-balanced class with individuals that are not well-balanced. That said, yes your chances of acceptance would go up significantly if you had a higher score. How much of an increase is difficult to say, with so little info about the OP.</p>
