Whichever college you are interested in will definitely have literature that covers the various types of engineering majors that they offer. Don't forget that online sources such as Wikipedia are a great place to look up things of this nature as well.
You can find a lot of information about the various engineering fields on the internet. General areas include; mechanical, electrical, civil, chemical as well as specialties like aerospace, automotive and mining etc. within these, there is gereral engineers support and project engineering. Sometimes universities and/business and/or engineering companies will address your class. If you are lucky a parent of a student may be an engineer who will go over their job or general requirements. Engineers are problem solvers....this can be your first challenge. Good luck!!
