Vet schools don't require students graduate with specific major fields of study to be considered for admission. They do, however, require undergraduate students complete at least one year of English, biology, introductory chemistry with laboratory, organic chemistry with laboratory, physics with laboratory and one semester of general microbiology with laboratory and biochemistry.
There are three possible standardized tests an applicant may take: the Graduate Record Examination (GRE), the Medical College AdmissionTest (MCAT) and the Veterinary College Admission Test (VCAT). Each vet school has different requirements so it is very important you conclusively determine the standardized test your potential vet school requires. As of 2010, the GRE is accepted at all vet schools in the United States.
It is important to familiarize yourself with the scope of these tests to facilitate what classes you should take as an undergraduate. You will find detailed exam objectives and syllabi for each of these exams at your college counseling center. You should start reviewing these materials in your sophomore year.
The GRE measures your ability to comprehend and evaluate written material, mathematical concepts and your ability to express thoughts cogently and effectively, all at the graduate level. While there is no specific undergraduate course or seminar you can take to score competitively in the GRE, undergraduate classes in English composition, arithmetic, geometry and statistics will provide sufficient foundation.
The MCAT is designed to evaluate a candidate's skill to solve problems, think critically, write cogently and asses the candidate's knowledge of scientific principles, all required to pursue graduate work in medicine. To score competitively, you must have sufficient knowledge in general chemistry, organic chemistry, physics, biology, English comprehension and English composition.
The VCAT measures your level of understanding of scientific material and your ability to communicate complex items effectively. To be competitive, you should have a strong foundation at the undergraduate level in biology, organic chemistry, inorganic chemistry, English comprehension and mathematics.
