Physicians, dentists, physical therapists, respiratory therapists, nurses, etc. are all members of a healthcare team. Demonstrate to admission committees that you are a good team player by organizing study groups and helping fellow classmates in lab. This assistance will be noticed by an instructor and will be noted in that very important letter of recommendation you will need in a couple of years. Do not be intimidated by large classes.

Professors have office hours and most enjoy getting to know their students.
When selecting your first semester classes, consider your own personality and interests. As you become adjusted to college life, changes in your schedule will be easier. If you will have a part time job, allow time for that and the commuting time to and from work. Plan two to three hours of study time for each hour you will be in class each day. Balance your course load.
