As everyone's said, the exam was a load of shit.
Every teacher around here I've talked to that teaches Engineering has said that they couldn't believe it, it's all very good an exam for an engineer, but a student? Pah.
We studied planes too, not helicopters, so I made most of that section up. Telecommunications, we never did Coax either, or UTP, but based on what I know already I answered that. And concrete cancer? What the crap is that?
The "bush" I actually laughed out loud when i read it and got in trouble, then just measured things around the page that were the same size with scaling.
All in all, that was a mockery of a test. I can't believe they gave us that shit. If everyone in the state goes really poorly, the upper half will get marked up high. /me crosses fingers
