What classes are required to become an astronomer?
A variety of astronomy classes and labs, naturally. Higher level math and physics classes are also a good idea, as well as some classes in other sciences such as chemistry and geology. Different schools have slightly varrying requirements, so it is difficult to give a more specific answer.
You aren't, technically speaking, required to attend college at all to become an astronomer. However, if you want to be hired as an astronomer and get paid as opposed to doing it as a hobby and buying all your own equipment, you should expect to minimally get a 4-year bachelor's degree in Astronomy or possibly Physics.
Depends on the type of engineer you want to become. Calculus and Differential Equations. Most of the schools have some basic materials classes that are required, as well as the mandatory English, History and Science courses. My school also required everyone take Mechanical Engineering and a Civil Engineering class.
There are no required courses you must take in High School. The classes required to become something are taken in college. High School classes are just used to give you a background into what you'll be studying at college. However, I would recommend you take a lot of art classes and maybe graphic designing if it's available.Â
There are no classes in high school that will help you become a game warden. Take science classes so when you go to college you will have the classes you need. You can major in forestry management or environmental studies to become a game warden. Since they are part police I imagine each state has a training that is required as well .
All exterminators have to take classes to become certified in Pest Extermination. During these classes they learn how to use the equipment and chemicals that are used in extermination.
