for reference, I'm a software development apprentice, so I get training for it and the tutor I have at the moment is

so adamant on coding HIS WAY (which is hideous, btw, because I spent a year at uni and he does so many things which I was told not to do)

and when I try to help my classmates because I have spare time and want to help them he butts me out of the way

to yell at them for not understanding in a condescending way

and do it for them such that they don't understand what's going on but it works and matches his solution (because he wrote it)

trust me, dude, I've been tasked with tutoring these kids at work

I know how to let them reach the conclusion without outright telling them the answer

and in a way that they understand
