At the beginning of a new semester you could print or write a schedule, but that piece of paper will soon be creased, sat on, filled with skin oils, and otherwise becrudded. Here’s my approach.
If you don’t know your cell phone’s e-mail address, look it up. Compose a new message to that address. Subject: Monday. Message body:
time class location ---- time class location [...]
Repeat for Tuesday through Friday.
Your SMS inbox should now contain five new messages, each with a subject line of the day and a compact schedule within.
