You will be about three times faster, hopefully. Don't expect to be able to do what Pete Bisonette did on the infomercial, where he read a work of Dicken's in like, 5 minutes. That takes many years of practice, and getting to that level at all is questionable.
Expect to go through material three times faster...in fact, if you don't you can return it for a refund.
