NET for UTH

Hello, I'm about to take the NET for University of Texas-Houston next week, 10/18. I was just wondering what UT is looking for their scores. I took the NET for TWU and they focused only on the Reading Comprehension. I bought the ERI's study guide, but I'm not sure if it's enough since it only covers reading and math. Should I go ahead and buy a different guide that covers science as well? Any help/tips would be greatly appreciated!
