Academic Excellence Center (AEC)
The Academic Excellence Center (AEC) is an educational space within the College of Engineering providing drop-in (no scheduling required) one-on-one and group tutoring by an experienced upper-division student tutor. The service is open to all students and is free of charge. We offer tutoring across a variety of course levels in the subjects of mathematics, chemistry, physics, computer science, and engineering mechanics.
The AEC is located in 323 Sackett Building, and the hours of operation during the academic year are Sunday, 2:00 p.m. to 9:00 p.m., and Monday through Thursday, 5:00 p.m. to 10:00 p.m.

No appointment, scheduling, or emails beforehand required!
