I took the TestCrackers GRE course and found it to be very well thought out. The curriculum is clearly customized for the exam, and all of the instructors were extremely knowledgeable about both the test format and the content. The classes were engaging, and my instructors, Seth and Marty, were incredibly kind, which made the learning environment genuinely enjoyable. I would highly recommend TestCrackers to anyone preparing for the GRE.
I really enjoyed taking the GRE prep course with Andrew and Seth. Through their guidance and program, I was able to increase my score by 10 points for the verbal and quant sections within 2 months. I took the GRE a week after completing the prep course. If I had started studying earlier and discovered them sooner, I would have scored better, but overall it was a great experience. You won’t regret it! And they truly want the best for you and will make time for you outside the planned classes if you need additional help.
I recommend TestCrackers to anyone looking to prepare for the GRE or GMAT. I took an online prep course with one of the Big test prep companies and wasn't satisfied with the result and the instructor. So I switched over to Testcracker after a call with Yuri. I took the Verbal with Seth, and Quant with Marty and they both made test prep classes actually fun and engaging! I learned key test-taking strategies and shortcuts that helped me with timing (something I struggle with) and tackling harder problems. Although I'm not at my target score yet, I'm hopeful I'll get there soon. Post-classes, I still felt supported by my instructors who gave me feedback on my study plan and also answered questions. Thank you!
Test crackers is amazing!!! I improved my score from 150 verbal and 154 quant to 166 verbal and 167 quant! I didn’t know this big of an improvement was even possible
TestCrackers is the reason I did well enough on the GRE to get into UC Berkeley. I cannot recommend Yuri and the experience highly enough!
I am writing this review years after taking a TestCrackers course with Seth and Yuri in Berkeley. I am now four years into a dream career that would not have been possible without a strong GRE score to get into a competitive graduate program. I strongly recommend TestCrackers for test prep - they are efficient, friendly, and extremely gifted instructors.
I researched every test prep service in my area for months before I selected TestCrackers. They had glowing reviews but even these couldn't do justice to the incredible level of detail and attention that they put into their work. TestCrackers made a HUGE impact in the trajectory of my life. I was working with an elementary understanding of basic math, and had only one shot to take the GRE before my graduate applications were due. I took the in-person quant course and received so much more than I was expecting. I think math can be scary, but their instructors create a very safe environment in which to learn. They meet each student where they're at, and they know how to move students through the learning process. I could see my progress from week to week. Their instructors are accessible, attentive, and provide so many resources to support learning. I was particularly impressed that they were able to prepare me for the GRE in such a short amount of time, and from such a LOW baseline. With their help, I was able to land a spot at a very prestigious graduate program on my first try. It would not have happened without TestCrackers. Choosing them was one of the best decisions of my life.
Highly recommend TestCrackers. They are GRE Prep wizards!
I started the course with a 580 on the practice exam and got a 750 on the official GMAT two months later. I did the virtual course with Seth and Marty and absolutely enjoyed them and the way that TestCrackers moved through the material. I highly recommend taking advantage of the small group tutoring hours that are included with the course. You get a great understanding of all the material that the GMAT covers as well as all the tricks that help make you more efficient. Of course you have to put in time studying once the class is finished but it felt more like refining skills gained rather than learning additional methods.
Had a great experience with the Testcrackers team for my GRE prep. Well worth the investment.
