There are several things that help when you want to learn more about jobs or occupations:
1) Research.
-Research can help with a lot of things. There are many websites that would be very beneficial if you look up your topic!
2) Ask.
-Asking or even interviewing someone with experience in your topic is another great way to learn about something! If you ask them, they would be more than happy to help you and you can still learn!
3) Volunteer.
-Volunteering is another great way to learn about your job field! Volunteers learn about different things that the job requires you to do and it’ll add value to your resume!
Hope this helps!
