By "messing around with it" Chang means that he hasn't made the effort yet to actually learn it and therefore hasn't applied it to his studies. In fact because he hasn't done the course in the order given he is now paying the penalty of having to sort it all out.
Use the tapes sequentially learn it for yourself and you will discover how useful the photoreading system really is for studying. I expect that you will be passing on the tapes to your brother in the future
