Testcrackers is AWESOME! I took the GMAT quant class with Andrew and verbal class with Kirk at Testcrackers. I received study materials on the day I started classes and had access to unlimited books from the library. They scheduled virtual office hours every week (outside of class hours) to help with questions.
The class is small (12 people), so we received individual attention. Besides, Andrew & Kirk did a fantastic job at engaging the class. Their tips and pointers in both quant and verbal really made a difference in-terms of saving valuable time on the GMAT. We also had short 5 minute breaks at the end of every hour to make sure the class recharged.
Overall I couldn't have asked for a better experience for my GMAT study class. Thanks to Andrew and Kirk, I'm going to my dream school (The Wharton School). I'd highly recommend Testcrackers for anyone who is getting started with the GMAT prep and needs a structured study routine.

Great experience!
Yuri and Seth are fantastic. I was able to improve my GRE score and get into my desired graduate program with their help. Everything about TestCrackers has a personalized touch. They provide materials no one else does. Go with them, not one of those big generic test prep companies. I would highly recommend to anyone taking the GRE! Thank you!

TestCrackers is awesome!!
TestCrackers is awesome!!! I had a great experience taking their classes in both the SF and East Bay locations. I found all the instructors to be incredibly responsive and they all seemed to care deeply both about my goals and progress in the course. The content they present really helps sift through some dense material. If I could do it all over again, I would have definitely wanted to be as shored up as possible on my GRE vocabulary...you need a good chunk of time to get all these crazy words under your belt, don't rush it/cram!

Definitely worth it
I had an amazing experience with TestCrackers. I attended the GMAT test courses and when I passed the test one month later I ended up with an even better grade than the one I was aiming for!
I should definitely thank the professor and the classmates for this.

Great Value and Tricks!
Had a great experience with TestCrackers, they taught me a lot of great time saving tricks with the GRE they made me confident in when to skip a question and when to double down.

Isaac is a phenomenal teacher that prepared me for my first GMAT exam. The TestCrackers team is friendly, smart, and accommodating. Isaac always made me feel welcome in class and like I could ask any question without feeling uncomfortable. I would highly recommend TestCrackers to anyone who is looking to hit their target GMAT score!

Couldn't recommend TestCrackers enough.
Couldn't recommend TestCrackers enough.
I graduated from college in '14, and so since I am only now applying for grad school in '18, I felt it was in my best interest to take some Verbal + Quant courses to freshen up before I took the GRE. The results speak for themselves, folks.
I read lots of great reviews on yelp for TestCrackers in general, but when choosing teachers I just went with the courses that fit into my 9-5 work schedule, and luckily both teachers were fab. I took Verbal with Kirk and Quant with Marty (Martin).
Kirk Schuler helped me bring my decent verbal score of 150 all the way up to 170 by the end of the course. She taught me to think like the test (I'm not traditionally a good standardized test-taker), and that seriously made all the difference. For those new to the GRE: the Verbal section is really unique in how it poses questions and prompts essays. I was an English Major in school, so I was used to responding in a certain way. Kirk taught me how to unlock the "coded" language of the test which 100% prepared me for the real deal. She was also just a cool person to talk to, and knowing how much I wanted to smash the Verbal test, she did all that she could to encourage me towards that goal.
As an English Major in school, Quant was then obviously my weak point. Marty Cinke was seriously the nicest guy/teacher--he clearly genuinely loves math (or he fooled me well, ha) and cares about each of his students. Even when the course ended he made sure we knew we could reach out for any help we might need preparing. He wants you to do well, and you get out of his class what you put in. I can't say I ultimately did as well on Quant as I did on Verbal, but I really believe Marty did the best he could with what little math talent I had to offer.
If you want to kill your GRE, TestCrackers is great--just be warned that just showing up in class isn't going to get you there. These teachers give you the tools you need to study the right way, and the rest is up to you.
Thanks Kirk + Marty!

Not your average tutoring
I initially took a TestCrackers GRE prep class (quantitative section) in 2015 when applying for graduate school. I was able to increase my quant score and I got into my top choice programs and top programs in the country for my discipline. I wanted to try to increase my GRE scores once again for Ph.D. apps in 2019. My instructor was kind, attentive, and funny ,the homework/helpful booklet was dependable yet challenging, and I increased my quant score once again. I received acceptances with funding offers to 2 out of 5 of the Ph.D. programs that I applied to and one waitlist offer to another (#covid). All programs are some of the top programs in the country. They say that a grad school application is a bit like a flower bouquet when it comes to components, and TestCrackers helped me feel confident with the GRE stem.
