MAKEUP LAB FORM
In order to make up a missed lab:
Fill out the middle of the form below
Have your Instructor/TA sign it. Your Instructor/TA MUST sign the form BEFORE you attend the makeup
lab.
Give it to the Hosting Instructor for the section you attend to make up the lab. Note: If a section is full,
students registered for the lab have priority. It is the Hosting Instructor’s discretion as to whether there
is enough room for you to attend when the lab is full. EVEN WITH the Instructor’s signature, the Hosting
Instructor is NOT required to allow you to attend that lab as a makeup.
Make sure your name is on the group list for the day.
The following are approved reasons for missing and making up a lab. Mark the reason for your request:
