The easiest and best way to catch up on material you missed in the lecture you didn’t attend is to ask someone from your lecture if you can copy their lecture notes of the day you missed. Don’t worry if you don’t have a personal friend in the lecture – simply turn to someone sitting next to you and ask them – you’ll make a new friend and possibly find someone to work with in the class.

Another option open to you is to read the text on the the topics you missed in class that day.

If you know you will be absent for an extended period of time, you should contact your instructor.
