Don’t go to campus on Mondays and Fridays. Instead, dial in all online work and use the free public library (which is quieter than the campus library) to study in peace. This will save $6-10/week in parking, $10-20/week in pocket expenses, and $5-10/week in gas. $40 x 16 = $640/semester saved. That alone will pay for books, copies, and office supplies.
Stay off campus until 4pm Wednesdays and pay only $2.25 instead of $5 to park in certain places. That’s a savings of $2.75 x 16 = $44/semester in parking alone. Don’t eat on campus and save another $10 x 16 = $160/semester. That’s $204/semester.
So, I’ll save at least $844 by avoiding campus as much as possible this spring. That’s almost an entire month’s pay.
