How long does it take to learn as new trick on a skateboard?

about a week, just keep at it and don't give up. SLAM down on the tail JUMP and SLIDE your foot up and let the board do the rest haha (meaning land and compress) -----------------------------------------------------------------------------------------------------------------

I am an AM turing PRO i like to teach people to really stomp as hard as they can on the tail of their board and then jump while sliding your front foot towards the nose. FOR A HIGHER OLLIE START WITH YOUR FEET CLOSER TOGETHER
