Thanks for all inputs.
I do have the handbook download from FAA website. Although the printed materials provide all professional details, I strongly feel the video can help to reinforce and accelerate my learning process through visual experience. Leaning to fly is a very practical subject and the visual experience just helps me a lot to understand what's going on in real situation.
It seems that every one has different recommendation when it comes to studied materials. Can anyone tell me more your personal experience for those materials, if you have any, such as what you like or dislike about those materials. I would appreciate that.
