Can't speak for them, but I encourage you to take a look at GMAT Pill as well. We've had many former students from these other programs who didn't get the results they wanted and found GMAT Pill to be effective for them.
Each course takes a slightly different approach - and what works for one person may not work for you. So explore around to see which approach resonates with you.
We take a "thought process" and visual approach - with expert demonstration videos that show the thinking process that goes on in an expert's head as they think through a test question.
We also look at many
variations on a core concept. For example, you may be tested on distance = rate * time with 2 trains moving. But what if 2 trains are not moving in the same direction - instead they are moving in opposite directions? What if one starts first before the other? What if one is moving north and the other one is moving east --- or maybe at an angle, thus forming a triangle?
So we cover the core concept - but also provide sufficient practice around that so you know the possibilities of what can be tested.
