GRE

Hello There,

I am new to Khan Academy.  I am 43yrs old. I am planning to go back to school to pursue my newly discovered passion (Economics).  For that to happen, I need to take a GRE test and then apply to my state university ( UofI@C).  However, you folks don't have any GRE test prep material.  Is there a reason for this? I see GMAT, LSAT, and even MCAT but no GRE.  

Please write back at your earliest convenience. 

Thanks.

Azhar

PS: I like what I see on your site so far. I added my son. He is in 1st grade.
