i am wondering, when certain items are covered in a lesson, and I complete all but say one. Or more precisely I completed everything in the first part of the core lessons. Should i hang here until I am able to fluidly perform those two items or should i be moving on while i continue to work on the two items.

I can do an A Major chord, but not so easily or fluidly like the others ..
I have a lot of trouble with the B Major Chord, I have to really look at my hand and place the fingers but now i can do the stretch so that's an improvement, I guess.

Should I be waiting until i can just go to them as easy as i do the other chords - - without even looking, or like i said just move on as I work them.

Thank You in Advance
