I agree with @pandabear68 I have heard that more 4 times starts to become detrimental - it looks bad and even if you get a higher score the 5th time it doesn’t carry the same weight. I wouldn’t take the ACT or SAT more than 3 times. Also, my DD had a 35 ACT and perfect GPA with maxed out AP classes and terrific ECs/service and she got $24k/year merit + $2k/year UASP scholarship for total of $26k/year. That’s still $4k/year short of full tuition - maybe they give more for a 36 ACT?!
