Gaining clinical experience as a premedical student is rather
important as it can show that your decision to want to go to medical
school is well-rooted, and not coming out of left field. Gaining
clinical experience, however, means different things to different
people. Simply volunteering at your local hospital may not be
sufficient, as these volunteer opportunities often have you do tasks
very unrelated to medicine (e.g. filing, faxing, copying). Look for
"Health Career Opportunity Programs," or other such internships
designed for premedical students, so that your valuable premedical
time is not wasted in a second-rate program. If your school has a
"premedical internship" program, take advantage of it.
