GMAT Strategy

Does anyone have a link to the person that did every answer for the 11th addition on YouTube? I used to have the link, but deleted it from my browser after finding out it was only for the 11th addition.

I can't seem to find it and just got my hands on the 11th edition after completing the 12th addition. I figure watching some problems worked out may not be a bad idea in my spare time.

Also, if you used this guys youtube videos, did you find them to be helpful?

2.5 weeks to go and scoring 650's on practice tests. I am happy with this for the schools I want to apply to but know that it can't hurt to do better.

Thanks
