Admit: Kellogg + Columbia
I first spoke to Sam in June last year before I gave my GMAT. Since then, Sam has been a mentor, supporter, and cheerleader in my application process. Even though I didn't work with him full-time, Sam was always there to provide me with the right guidance I needed. To summarise, I would 100/10 recommend getting Sam's services in case you're planning on cracking the top business schools.
