Just give up man, you dont want to be a professional engineer, what you want to be is a Steem Engineer! :P

Best of luck man, I wish you the best.

Adults are more biased, young adults kind of study without too much critical thinking, while we now start to doubt some things on our textbooks as most of them are written by people who haven't really updated their knowledge too much.

At least that's what I feel.

Cheers!
