Prepare for the lecture
The greatest advantage is that
you are familiar with the subject
you know what to ask
you are not going to waste time by writing down stuff that is already there in your study material. Rather, you know what to write, where to pick links and to clear your concepts.
By the time the lecture is over, you are in a much clearer state of mind. This way, taking down notes becomes more meaningful and worth the time you spent doing it.
This may take a little bit longer but it will work. Just give it a chance. When you are taking notes change the color of your pen! Don’t write in blue or black ink. Writing in color will help you retain 50% – 80% more of the infomation without reading it a second time (also highlight in purple). I am a teacher of adult education and this is the rule for my class room.
