Her AI (roughly) based on the information you provided is a 208. That is quite low for an Ivy–but not an insurmountable problem for a top recruit. . Further there are no bands in Ivy recruiting with the exception of football I believe. The band system is NESCAC. I looked the concordance and an SAT of 1350/1380 is equivalent to a 28. The SAT is generally a harder test with more time per question. The ACT is much easier but fast. So the difficulty of each is based on different aspects of the test.
