Anything mentioned in lecture has a very high priority. The more time allocated to a topic, the more time you should spend studying it. You should be able to use terminology and symbols used in class in a conversation. Hints and gestures from the instructor will highlight important information. Questions that your instructor asks are clues as to what you should learn.
Specific assignments indicate what material is important.
For most students, the two most difficult adjustments to college life involve discipline and direction. You must develop an effective pattern of study and stick with it throughout the entire semester. Discipline means that you attend each and every class meeting, on time and attentively. Arrive in class a few minutes early to get organized and spend a few minutes reviewing your notes from the previous lecture. This will get you mentally prepared for the session and refresh your memory.
