Note: Of course, you can go to the traditional way of independent activity and write notes yourself, but it’s easier to unite with your bandmates and make life easier in the semester. By cooperating with fellow students, you can assign responsibilities for working with abstracts between each participant in your “working group”. For example, as an option, do so: someone makes records on even days, someone on odd, some write the first 30 minutes, others write the next thirty, etc. Especially the second option will suit a more lazy student, who often get tired hands, or those who can not always keep pace with the speaker’s fast pace of speech. Of course, this method of teamwork has its own disadvantages. Secondly, not always, but, as a rule, rarely, the handwriting of your classmates will be a work of calligraphic art. And it is likely that you will spend more effort on deciphering “secret records” rather than independently managing them. Each student has his own way of highlighting key and important points in the teacher’s speech. Therefore, that for some it will seem important and significant, for others it will be banal and unworthy even of an easy note in the abstract.
