I understood that those courses were upper-level/graduate courses like the program at Texas A&M. Plus SMU is private and the scholarship they offered me only covered half of tuition while UTD im going for free plus extra for rent.
sleep early, play lots of hallway bolling (empty waterbottles and a tennisball), take breaks often when studying... do *NOT* try to 'get in alittle extra' right before the test.
sit in front of the class, introduce yourself to the professor or aide - its a good way to start things off and shows your interested to be there, even if your not.
BEST advice from the list so far.. If i was with your shoes i will definitely go for these ones. Also some note from the other guys as well..
