**Myth #3:**
"Freshman year doesn't really count. I'm just starting college. Besides, I can repeat any courses I did not do well in."

**Reality:**
**ALL** grades count, although medical schools will look at the overall trend of grades. They will analyze a transcript and examine the number of courses per semester, course levels, number of science courses and academic performance. A strong upward trend in grades is necessary for applicants with a weaker, earlier, record.

Repeating courses for medical admission is generally not recommended as repeated courses for MD admission will be averaged. Instead, the schools would prefer to see students take advanced work in the same subject and do well.
