I am eligible for a pell grant, why did i not get one in my award?

i aspire to got to UT-arlington, and i just checked my student account online and it say i've recived a $3000 value workstudy. thats all the aid i got my EFC is 966, and it says on my SAR i'm eligible for the pell grant why did i get only workstudy, or are the grants still to be awarded. should i be worried?
