Acceptance of make-up labs is at the discretion of your instructor. It is recommended that you check with your instructor and lab staff and sign a log prior to coming in. It is not necessary, but it might save you an unnecessary trip.
Arrangement for other hours is usually possible but requires advance approval from lab staff.
You need to bring a copy of your instructor's lab write-up with you.
For questions, first check with your instructor. Additional information is available from:
