Personal education with orientation in the student, not in the subject. I can change the rhythm or the way to teach watching the necessities of the student. The most important part is learning the objectives, not to memorize the subject and don't understand what the student is involved. This different way to focus the lessons during this period has done the success of the 95%. I prefer a long term that a short one with stress and not much planning for part of the student. The best way to learn something is assimilating what we are processing and arousals the passion in the student, not like an imposition or something boring and mandatory.
Short classes are better than long ones.
