Preparing yourself to become a doctor takes several years. This includes not only years of college and residency training, but also encompasses the classes you take in high school. Take classes that will prepare you to succeed in your college classes as early as possible. This will help you to graduate on time and begin practicing as a physician.

Science

Take as many science courses as you can during high school. Focus on the life sciences if your school offers several choices of sciences in high school. Take as many levels of biology as possible. Chemistry is another very helpful course to have under your belt before you apply to college and medical school. Physics is also an important science to study in high school for future doctors.

Math

Upper-level mathematics courses will also prepare you for college entrance examinations and standardized tests, such as the SAT and ACT. Concentrate on getting to the highest level of calculus and other similar math courses during your high school career.

English

Advanced Placement or honors English courses can prepare you to communicate effectively in a written format. You will take plenty of notes and create written records for your patients as a doctor. It is vital that you understand how to speak not only to others in the medical community about patients, but that you can communicate with your patients in a way they can understand as well.

Electives

Choose electives that genuinely interest you. Doctors use their hands all the time, so a course in art --woodworking or sculpting, for example -- can help you hone your motor skills. If you take theater or journalism, you can develop your communication skills, which are important for a doctor.
