<p>Yes, it is possible. I went to a small, public, state school and I will start graduate school at an Ivy in the fall. I’m not trying to sound arrogant but I want you to know that you shouldn’t lose hope. I was once in your position in h.s. (perhaps I even did worse) but I bucked up during undergrad. and everything has worked out.</p>
<p>Grad. school takes a much more holistic approach so research, ECs, and letters of recommendation are HUGE whereas GRE/GMAT is only a small portion. </p>
<p>Best wishes and best of luck to you =)</p>
