High school students interested in a career in zoology, particularly ethology, should focus on taking advanced science and math courses, including AP or honors chemistry. A strong foundation in chemistry is crucial, as most biology programs require general and organic chemistry. Students are encouraged to participate in science competitions, especially those affiliated with ISEF, to gain practical experience. It's also important to research colleges with strong biology and chemistry programs, ideally those with ACS accreditation. Preparing academically in these areas will enhance prospects for a successful career in zoology.
