precal · Answer

need to do your homework and strive for doing it to understand it.  Do not do the homework for the sake of completion but for understanding.

ok which is the best method book /online videos?

precal · Answer

I like to use my math books but I also, like to watch online videos when I need clarification.  I always refer to the books-authors have to go through a process for a book to be published.  ie verification of math facts.  Videos can have mistakes and even when people point them out, very few people correct the videos.  Even Khan has a mistake on quotient rule in the calculus section.  He named the video quotient rule but never used the actual rule in the video so I think he should have name it "an alternative to the quotient rule".  Anyways videos are good way to hear and see the math....
