Science Buddies: "Ask an Expert"

I'm an undergrad physics major and will be applying to astronomy grad programs this fall. Other than the obvious (grades, PGRE, letters), is there any good advice that I should consider?

As a note, I have a 3.65 GPA from a small school (UT-Dallas). I've been doing research for over two years (~1 year in material science), have done two posters (3rd coming next semester), will be submitting a paper next month, have a research related scholarship, have won 2 research related undergraduate grants through my university, and might be giving a talk at a conference in December. Any thoughts on how I may stack up to candidates at some of the top tier programs?

Any thoughts or advice will be greatly appreciated!

Hi Joaquin - this forum is for K-12 students doing science fair projects, so unfortunately this isn't the right place to ask your questions.
