Kelley School Direct Admit Question

my son was just granted direct admission April 5th. IU admissions had his GPA incorrect in the system. His grades are on a 100 point scale. Not sure what exactly went on - the administrator in the high school guidance office contacted the look rep and had it amended. In any case, we were just at a red carpet day and were told that you could get your grades up and still be directly admitted. The deadline is the end of July. You could also take the SAT again if you need that score higher too.
