What are my chances to UMBC and all the other colleges?

<p>I got 1580 which is very low SAT score...
However I have GPA of 3.7 and 4.4.
I did NHS and many other extra curriculum activities.
I also have 300 student community service hours.
If I write a good essay and have good teacher recommendations,
what are my chances that I will get in to UMBC, VCU, and GMU?</p>

<p>(I want to study in like chemistry, biology, etc subjects....)</p>
