We all use these techniques one or all at one point of time. I certainly used many though never called them with those names. Having this techniques available on YouTube is great.
One can easily pick them and keep them in his or her study arsenal.
AeSI exams are first approaching, I think its a best time for AeSI students to visit this YouTube page and spend an hour to renew these study techniques.
