that’s about right except a good trade takes about two years and if you get in a union apprenticeship program you are debt free. The unions are looking hard for folks as people are are not as interested in real work as they use to be. When I was young you had to know someone to get an apprentice position, not anymore.
Get a certificate or Associates from Lamar Institute of Technology in Beaumont Texas and the refineries will knock your door down trying to hire you.
Other schools in other states have similar programs.
Don’t get ripped off by Phoenix University or DeVry though.
Join the Nav,CG or the AF ,learn a trade and let the GI Bill pay for more training if you even need it for a firm to pick you up
