What college classes are required to be a podiatrist?

Since each school may have different requirements let me answer the question this way.

To get into Podiatry school you need to take the MCAT. The classes you need to take to do well on the MCAT include:

General Chemistry (2 semesters or 3 quarters) +lab

Organic Chemistry (2 semesters or 3 quarters) + lab

Physics (2 semesters or 3 quarters) + lab

Biology (2 semesters or 3 quarters) + lab

Additional classes you might want to consider are:

Critical thinking English class (Verbal section of MCAT)

Biochemistry

Many schools require a minimum of a bachelors degree. Your degree does not need to be in a science field, but it wouldn't hurt. Take note that the classes above are all considered "lower division" so majoring in a science major doesn't mean that you will get out earlier.
