there is alot of different things that isnt what people think it is. Like the space program, we think they have huge ships that can carry 5000 passengers but in reality they have a space shuttle that can bring 6-7 people out in space.
Change our mind is our right, so its nothing we should talk bad about and information is power (makes it easier to choose a way to walk) 
I have never got a math head so i suck at it. Also known as -not sure what way to go- I have more general knowledge about most things instead.
From what it looks like in the job area i have to go throu the torture of getting wood taste for hours each day again. Hate sit on a hard chair for hour each day, there is 10 000 better things you can do. I dont swallow the fancy talk that -you can have fun after-, a well known fancy comment is that you can live life when you are retired ?!?!
(In reality life is dead when you are retired, too tired or worked out to be able to do anything close to live)
I dont know if i lost the subject but i hope you manage to understand it 
Hey, I'm not that stupid to expect that the days there are spent by developing plasma weapons and killing aliens, but I have expected that constrictions, manufacturing, testing and so on would take a portion of the "work" but it's more like 99.5% theory mixed with extremely complex and boring theory and 0.5% practical part.
And yes, do boring work 8+ hours a day so you can have a hour of fun a day is kind of grim vision of life. And "Enjoy once you retire" that's outright black humour (Well, except for Greece, you retire at like... 39 so there's plenty of life left. Also might've something to do with their bankrupt).
And that is why I quit the shool and became proffesional freelancing lazy Jack-of-al-trades, haha.
