Hi TargetPhD,
This is a very old post. Please keep in mind our Quant Program today is even better than it was in the past -- by a significant amount.
We now have:
[*] Higher quality videos with animated cursors and hand-drawn math explanations so you can see our real-time thought process and approach as we write down the math
[*] Video solutions for OG13 math questions:
https://www.gmatpill.com/official-guide-gmat/[*] Dedicated video sections for common topics (sequences, rates, combinatorics, etc) -- each with multiple variations around a core question so you know what to do if you see a similar-looking question with a slight twist to it <---this is how you really learn.
[*] HUNDREDS of extra practice questions throughout the course that were not there before -- each complete with video walkthrough explanations
[*] Bonus advanced material on more interesting/complex math scenarios -- such as poker probability -- for those interested.
[*] Mobile Access via iPad / iPhone / Anndroid apps with offline video download capability (search "gmat pill" in the app/play store)
Here are a few users who have shared testimonials with us -- including links to their official score report showing their quant improvement:
