Preferably, the admission test should be taken in the spring of your junior year, since that permits early completion of your application and will allow you to correct any deficiencies by taking the exam again in the fall if necessary.
Grades are the most important initial factor in the selection process for most professional schools.
However, different schools place varying emphasis on the results of standardized tests. In general, slightly low DAT, MCAT, VCAT, GRE, or OAT scores can be offset by relatively high GPA's, but the reverse is not as effective. These tests, together with the GPA, letters of recommendation, extracurricular activities, personal statements, and the results of professional school interviews are used in selecting professional students. As has been stated for the GPA, there is no set cut-off point for admission test scores. If you have concerns about your scores or your test taking skills, please see the pre-health professions advisor.
