What classes do you need to take in high school to become a pharmacist?
You should focus on college preparation courses, particularly math and science. If your school offers AP classes, you could skip some of these courses in college if you get a decent score on the AP exam. It would also be a good idea to start getting some experience in pharmacy or general healthcare by shadowing a pharmacist or doing volunteer work at a healthcare facility. Contact an advisor at the pharmacy school that you are interested in and find out what their program requires.
