I went and visited the FA office back about a month ago and this very nice & helpful lady (I don't want to post her name on the internet...but considering there is only a few people who work there it probably isn't hard to figure out who I am talking about) that I spoke with told me that they do not give out the "need-based" scholarships and grants until June. A couple of other people have also spoken to this particular lady and found her to be very helpful, too. My guess (and this is only a guess) is that they wait to see who is definately coming to UT (according to the admissions office we have to sign some sort of commitment or intent letter in June) before they start giving these out. Also, I think I read somewhere on the website that like 80% of their scholarships and grants are need based.
Now I am putting together multiple pieces of information from different sources at UT Law (admissions office, FA office, website, etc.) so take what I am saying with a grain of salt...but I wouldn't freak out yet.
