Come to the Think Tank, a newly-redesigned quiet study room on the 4th floor of the Science Library. The rest of the 4th floor (and the 3rd floor) of the Science Library are also designated quiet study areas.
If you’re in search of peace and quiet on North Campus, try the Main Library. The 2nd, 3rd, 4th, 5th, and 7th floors of the Main Library are for quiet study.
Good luck with finals!
