But those younger ones who come to class with a hangover and just want to mess around all day are just a bunch of cretins. It doesn't matter a hoot about the teacher making allowances for them in their final marks etc etc.
A piece of paper may get a kid a job, but how long before the employer realises that the piece of paper means Jack when the kid can't do the job properly ???

The proof of the pudding old mate, is in the finished product......whether you can do the job properly or not. Any employer will tell you that.
I was a Master Builder before I retired, and I got there by hard work and study and applying myself properly to my work. I knew when my brickies were no good.....knew within 5 minutes of them being on site.....never cared what their qualifications were or what their bits of paper entitled them to do.
If they were no good, then they were booted off the site.

They run and cry away to the union......so what ??? What could the union do to me ??? Nothing !!!! So I'd lay the bricks myself.
If you are good at what you do, then anyone will hire you.
