Focused Content + Continuous Feedback

The first time I took the GMAT (2013, undergrad), I scored a 710. I started studying again a few months ago and tried all the prep materials out there: Manhattan’s practice tests, Veritas’ question bank, Magoosh question bank, etc.

Target Test Prep had exactly what I needed to crack the 700 barrier again and score a 730 - categorized quant content, study plans (long or short depending on timeframe), and a continuous feedback loop. I actually kept a spreadsheet where I classified each incorrect answer (geometry, number properties, etc.) as well as the reason that I got it wrong (stupid mistake, poor understanding of content, etc.). TTP had this built in, which really helped focus my studying with the limited time I have. Their approach is by far the best, and has an excellent price point.
