This means hearing what your professor is saying and trying to anticipate what he or she is going to say next. This may help you understand and follow more closely. If you have to miss class, let your professor know. It is very helpful to have a reliable classmate from whom you can get the notes. Exchange phone numbers so that you can rely on each other for notes in case of an emergency.
Proper note taking skills can facilitate understanding of lecture material.
Try not to write everything down. Be concise and sum up lecture material in your own words whenever possible. Write down unfamiliar terms. Review your notes as soon after class as possible. You can fill in details that you missed and review the material while it is still fresh on your mind.
