Submit SAT or ACT?

<p>I took both the SAT and ACT and did exactly the same on both. (31 ACT which is equal to a 2040 SAT) I think I might want to submit my ACT because for some reason the mid 50%score ranges for the ACT seem lower than the middle 50% for SAT at the colleges I'm applying to. (I'm not sure why they don't equate to the exact same amounts but they don't)
Do you recommend I submit my ACT or SAT since I did pretty much the same on both and while the score ranges are a bit different its nothing significant? Do colleges really weigh them both the same? I just don't want to be at a disadvantage because not that many people submit the ACT (in the grand scheme of things) Should I just send both?</p>

<p>Any advice would be appreciated!!!</p>
