Editor's notes

• If your GPA is 2.75 or higher, you're admitted automatically without a test score, as long as you're on track with the course pattern. Put your effort into finishing by Dec. 1.
• Check your major first. Nursing, Engineering, Business, Aviation Flight and Music all add a screening step, and Nursing starts only in fall.
