TTP - Likely the only prep course you need (70 point increase in 4 weeks)

TL;DR - Some of you may be in a similar circumstance as me: absolutely swamped with work, little time to study, looking for a self-prep track on a budget, but needing to relearn some essential math skills after graduating college almost a decade ago. TTP was a life saver and is the real deal. They have high reviews (which made me slightly suspicious like many others) but thankfully I took the plunge with the 5-day trial, continued on for the flex plan, and scored a 720 (70 points improvement) after 3-4 weeks of studying. Would highly recommend others prepare much further in advanced - there is no reason you can't score a Q51 with this program honestly.

I'm in the military and was deployed for several months up until R2 applications were almost due. It was not feasible to effectively study much out there due to the conditions (disparate connectivity, constantly moving around, working 100+ hour weeks, etc.). By the time I returned home, I found myself in a situation where I was already mentally exhausted from the deployment, applications were due in ~6 weeks, and the one practice test I took lacked the score I knew I needed (I scored a 650, but knew I needed a 700+ minimum for T10). I had read through a few old Manhattan books from a friend, made some flash cards to pull out when I found 5 mins here and there, and completed a handful of practice problems with the OG books, but didn't feel like I was improving really. I had already been checking the GMAT club forums every so often while I was out there and many people recommended TTP so I decided to give the 5-day trial a run. I liked the format and easy-to-understand presentation of material. The price was also perfect and offered a self-paced plan I could tailor. I continued with it and crushed through the Quant chapters, skipping many of the review tests and other pieces along the way since I only had a couple weeks to wrap it all up for the test and applications (would recommend others actually complete all of them).

I finished the Quant material in ~3 weeks (1 week before scheduled exam), reviewed a few of the chapters and note cards I made along the way, and then took another practice test 3 days before the test. I scored a 710 on the practice test, under less than ideal conditions, but was satisfied. I felt much more confident on the Quant and reviewed the one-slider recommendations for the AWA section they provided the day before the test. Rolled into test day confident with Quant and scored a 720. I attribute the simple writing structure formula partially for my perfect score on the AWA as well.

Overall, great and simple content at a budget price. VERY thorough and will take a ridiculous amount of time to go through if you complete everything, but I can almost guarantee if you actually completed all the content, there's no reason why you shouldn't score a Q50 or Q51. I can't speak towards the VR content as I largely skipped that for the sake of time.
