* Biology: Including general biology, cell biology, genetics, and potentially microbiology.
* Chemistry: General chemistry, organic chemistry, biochemistry, and often analytical chemistry.
* Physics: Usually general physics.
* Mathematics: At least through calculus.
While a biology major is frequently chosen, other science majors like chemistry or biochemistry are perfectly acceptable and often provide a solid base for medical school. The most important aspect is achieving a high GPA and strong scores on the MCAT (Medical College Admission Test).
