I paid for a classes to get my fundamental engineering exam. Can I claim that?

Possibly.

Contact the school and ask if they fit the description below:

"Eligible educational institution. An eligible educational institution is any college, university, vocational school, or other postsecondary educational institution eligible to participate in a student aid program administered by the U.S. Department of Education. It includes virtually all accredited public, nonprofit, and proprietary (privately owned profit-making) postsecondary institutions."

If they do, ask for a 1098-T or if you have an exception to getting one, in which case the expenses may be entered without a 1098-T into the TurboTax program.
