I am a senior in college and have a job lined up next year but thought taking the GMAT would be a good idea while I have the free time. My job is in investment banking and I heard about GMAT Pill through Mergers & Inquisitions. I signed up for their 1 month study plan in mid December and got a 590 on my first diagnostic test. They have great videos and break down what you really need to know for the test instead of flooding your brain with unnecessary formulas, acronyms, etc. I took another practice test a few days before the test and got a 710, so I went into the test thinking I would be happy with that score. My IR score on my first diagnostic was 4/8 and then I got 8/8 on the actual test. I got 98th percentile for Verbal and 78th percentile for Quant which somehow combined to be the 99th percentile overall and I owe it all to GMAT Pill- only one month of studying! Not to mention it's far cheaper than the big names.
