Corporate Finance Institute, good resource or not?

Hey all, just wondering if anybody has gone through any of the free courses offered on the corporate finance institute website, and would be willing to share any feedback that they may have, good or bad. I am going to be starting at University in the fall at a non target in NYC, and am looking to do anything to get a head start on learning the ropes of investment banking.

I would be very interested to hear any feedback that anybody may have about this website.

Thanks
