I want to get into a math phd program...help !

<p>Okay so I go to the university of Georgia and I am a double major in math education and math. I want to get into a really good grad school but I'm not sure of my chances. I would love to go to somewhere in New York like nyu or Columbia, which is a stretch, I'm sure. But I would also be okay with a top 25 school like UC San Diego or something (anywhere out of the south and with a pretty view,really)</p>

<ul>
<li>20 year old female
-GPA: 3.88 (but all A's the -A counts as 3.75 at UGA so I have all A's with a few -A's)
-Research : I'm doing research under a well known research professor starting in the fall.
-GRE: haven't taken it yet but im going to study my ass off and get in the 800's... I hope</li>
<li>I am a substitute teacher (I have done it for the past two years....doubling up on my tue/thurs classes and subbing on mon/wed/fri)
-I am also a paid math tutor for UGA</li>
</ul>

<p>*** I want to be a college professor in math</p>

<p>Other than that I haven't don't much more to prepare for mathematics phd program !
I still have 3 years at my university, so please give me some advice on how I can better my chances.</p>
