What are 'good' scores if you're looking Ivy League?

<p>I've only taken one subject test (the Literature in May) because I figure it's better to wait until June when we will have actually covered the material in class. I plan on taking Math 2 and Biology in June, so what kind of range should I be aiming for if I'm looking only at the most selective schools? SATs I'm not too worried about, I got a 2250 on my first/only try and I'll take that again next fall to hopefully get a 2300, but I really have no idea how the SAT 2s are weighted/looked at. My Literature was a 730, so would that suffice? Obviously there are other factors, but I'm interested in this particular aspect only.</p>
