GMAT Pill was the first course that I purchased for my GMAT study, because of reviews that its method is unique and targets busy professionals who don’t have a whole lot of time to study.
I purchased the 6-Pill combo, who contains everything from verbal to quant to IR.
I began with the Sentence Correction Pill. Lesson videos are divided into 10 core frameworks, which do not correspond exactly to the grammar rules categorization as seen in other review materials. Therefore, while these lessons did give me an idea of what to expect on the GMAT SC, I had trouble having a clear picture of all the grammar rules and concepts that were being tested. In addition, the depth of the discussion on specific grammar rules does not go as deep as in other materials.
For CR, GMAT Pill introduced a unique thinking framework. But with different categories and types of thinking framework, conclusions, and question-types, the problem-solving process does get a bit for me at times. As a result, the problem-solving process wasn’t easily applicable and a lot of effort has to be spent on memorizing the types of framework, conclusion, question types, etc
For RC, I couldn’t comment too much on it, as I believe for this particular section everyone’s reading strategy will be different. A thing to note is that there are a couple videos where we can follow the reading and thinking process of the instructor in answering the questions, and I believe these videos were pretty helpful.
For quant, similar problem persists. I believe the discussion on each topic is not categorized in a way that is easy to follow. The depth of the discussion also left a lot to be desired.
Overall, I do not think GMATPill is a bad product. It is just not for someone like me who need a more thorough discussion on each topic. For someone with solid fundamental on verbal and quant, and usually performs well on standardized tests, I believe GMATPill could be of a good value.
