Does my March 28th 2011 GI Bill payment cover March or April?

[Just Me]

I get my Post 9/11 GI Bill benefits around the 28th of every month. Is that a payment for that month or a advance for the next month?

I started classes around January 20th, and recieved full payment of benefits on January 28th. If my classes end in the middle of May, is Aprils payment going to be my last one? Or would I recieve a partial on May 28th?

Thanks in advance

Previous Month.

So, on the March 28th, it would be for March.
You should be receiving one for May on May 28th.
