Absolutely!
I have been using it for 3 yrs. very successfully.
Just make sure your goal for listening very clearly reflects your thinking. I find it works best if it is stated in 1 sentence.
Then just forget about it. Really, forget about it.
I used it recently w/ a particular course that was intimidating to me. I did not even attempt to begin studying until my attitude changed. I used PG for about 7-10 days (off & on). Result: I just picked up the book & started activating it w/o much effort.
First i used PG to get myself interested in dull material.
Then i used PG to get myself motivated to tackle it b/c it was 700+ pages long.
Then i used PG to understand RAS b/c that was a big problem.
Then i used PG to hone in for stuff that needed to be learned for the test purposes.
It worked! Good Luck!
