My daughter is a freshman and did not get into CSE Honors despite having a 34 ACT, 1520 SAT, and 3.97 GPA. That said, she also chose not to be in PSEO because she wanted to enjoy her senior year of high school. She is now glad she was not in CSE Honors, and I don’t think it is classic “sour grapes”. She likes being in the Frontier LLC rather than Middlebrook where there have been some flooding problems and some freshmen have been moved. She also is really enjoying both her classes and the students in the Frontier LLC. She seems to be enjoying college because she is able to study and make friends and go out.
I wouldn’t worry too much about getting into Honors. What you do want to do is sign up for housing as soon as it opens (usually in November) so that you have a good choice for housing.
