The MiT admissions page says that there is no preference between the SAT and ACT tests. However, the Cappex admissions estimates page seems to indicate otherwise.
I got a 2140 on the SAT, and my chances aren’t great just like everybody else. The ‘blue bar’ is in the range of the high second bar to the low seventh bar (about 28 - 70%). It’s a wide range, so my chances aren’t very accurate to begin with, but this doesn’t explain what happens if I change my score to the ACT equivalent of a 33 composite (according to http://www.berkeleytutors.net/conversion/).
If I change my score to a 33 composite, my chances jump to about 40% min - 80% max. Does this mean that if I take the ACT and get a 33 composite score, all other things remaining equal, I would have better chances to get into MiT?
