Check here to see what will be on offer next semester. Registration for rising seniors begins on April 9th, April 10th for rising juniors, and April 11th for rising sophomores. You'll only get until the 13th to finalize your choices, at least until the next semester actually starts, so expect to see a deluge of "What do you guys think of this class/professor/major?" questions on your Facebook home page over the next two weeks.
