Flawless

I took the Target Test Prep GRE course after scoring 162 on Quant (I needed at least 164, ideally higher for my applications). Before, I had tried to prepare for the test using the ETS GRE course. The difference between that and TTP is night and day.
Some highlights for me:
Detailed methodologies for solving questions quickly and accurately: for every possible type of question TTP provided detailed guidance on how to solve the questions quickly and accurately. This was invaluable for topics where I was routinely getting questions wrong or running out of time.
Huge question bank with solutions to every single question: I did around 700 practice questions on TTP, and still had some to spare by the time I took the GRE. Every single question has really great guidance on the solution. This was super helpful in improving continually.
Holistic approach: TTP not only gives you guidance on how to solve questions, but also on all other areas of test taking. Not sure whether to take the online or in-person GRE? TTP's got you. Unsure about your preparation strategy? TTP's got you. Test day nerves? TTP's got you. etc. etc. for every single area you could think of.
Bottom line, this was an absolute lifesaver and well, well worth the investment. Kudos to the TTP team for a fantastic product!
