A BYU experience is unlike anything else. The things that you will learn go far beyond what is taught in the classrooms, and the people that you will meet are exceptional. Researching the school, and being familiar with the rules and expectations of students, will make the transition smoother and help you get the most out of your BYU experience.
Talking with people who have attended, reading books such as this one, and looking at the BYU Web site (www.byu.edu) are all great ways to make sure that this is really the school for you. If you decide that BYU is what you want, then jump in and enjoy it! You are in for a great and character-building experience.
