How soon should I receive my financial aid after I receive my SAR ?

Question

I just turned in my documents that I needed to turn in today. Proof of my citizenship into my financial aid office. My EFC is 0. My aid is for this summer. I'm just starting college this summer and want to know how soon will I receive my aid after everything is turned in ???

My tuition and books total is about $636.00 for this summer. Do you think I'll get a refund on my financial aid if my EFO is 0 ??

Thanks a bunch !!!
