The search for the ideal way to take notes is an illusion, unless/until we regulate learning from the beginning of education, everyone will develop their own way of doing learning, including note taking. Successful note taking its therefore a matter of individual and subject matter factors.
There are however two criteria that I think are helpful in guiding people.
1 is the question of the purpose of the learning, and the use you will make of the information. Notes for an exam are different from other sorts of notes.
