Thank you,
Peterparker2! I'm glad that the video has been helpful.
I've never actually taken TTP's course -- or any other courses that are currently on the market. So unfortunately, I'm not remotely qualified to offer guidance on any of those courses. I simply don't know enough about them to be helpful.
The good news: TTP has been reviewed and discussed hundreds (thousands?) of times here on GMAT Club. I'd recommend starting with those reviews and discussions, and see where that takes you. You could also just hop into the GMAT Club chat room, and odds are good that you'll find fellow test-takers who have plenty to say about TTP. They'll be far more useful than I am on this.
I hope that helps a bit, and have fun studying!
