Truly not much difference in academic quality between UMN and Purdue - go with best price. Also location (if you like urban) is much more appealing at UMN. However, be aware that the CS program is not direct admit. You will need to take a certain number of classes prior to applying for the major and attain a 3.2 GPA or recommendation if lower gpa. It is an attainable goal - CS classes are tough but I don’t think as much weed out as Purdue.
