Don't rely on recording a lecture or reading someone else's notes. Take notes in class even if you do record. When you listen to the recording, simply add to your base set of notes. If you miss something, skip a line or two. After class, get the info from a classmate or the instructor.
Review notes frequently, both alone and with a study group.
Compare your notes to another student's. Sociology headings, questions details, answers, definitions Record the date and class at the top of each sheet. As you listen to the lecture, write your notes on the right side of the margin. After class, write key terms, topic headings, and questions in the left column. To study, cover the right side and use the headings and questions on the left to quiz yourself.
