Square One Prep IS the best.

I first called Square One Prep last Fall. I was referred by a friend who'd had success partnering with them. The owner was mighty impressive, and I wanted to sign up, but because the price tag was tough to swallow, I chose to partner with a less expensive group.
I worked with my consultant for three months, but never felt fully supported by them. Three weeks before I submitted my applications, concerned that my work was showing that lack of support, I reached out to Square One's owner. I really didn't know what my next step should be. The owner sensed that and offered to review my body of work - for free - and give me an honest assessment. She clearly spent several hours. When she walked me through all her comments, which took more than an hour, I probably should have been distraught by how much work I realized I had ahead of me. I instead felt a sense of relief because I finally felt like I had an expert at my side, guiding me. On the spot, I hired Square One and stopped working with my other consultant. Not once did I think about the new cost. Square One more than earned it. And I learned a lesson. With mba admissions consulting, what you pay for is what you get.
When I got offers from Columbia, Kellogg, and Wharton, my first call, each time, was to Square One because I knew that had I not worked with them I'd have gotten no offers. For something as important as an MBA, it's not worth compromising on anything, especially an admissions consultant. I got offers in the end, but I should have worked with Square One from the beginning! Thank you Square One!
