I do mechanical engineering. Typical day started at 9am and finished at 1pm, apart from when I had a lab/practical in the afternoon, which would last for 3 hours.
In first year I learned about maths, statics, dynamics, fluids, electrical circuits, heat transfer, design, technical drawing, and practical skills. My favourite subjects were maths and hands on, practical stuff. My best grades came from maths and electrical classes. Teaching has came solely from lecturers with PhDs who all speak very good English and many have plenty of industrial experience, too. Lecturers all have plenty of time for you, apart from the alpha dogs who are like world leaders in their field but they vary rarely teach undergraduates though.
My fondest memories were actually of nights out, the shenanigans that took place after said nights out, and getting ready for nights out, as well as all the pranks and other stuff that took place on nights in, and watching films and stuff with flatmates. I didn't have a particularly high opinion of having to drag myself out of bed on a cold, dark November morning to learn about dynamics at 9am.
I did a placement at an oil company in a more management sort of role and it differed from university in that you don't use anything you learned there. It was mainly, as already said, management, checking drawings and specs and arranging for other people to actually do the work. Coursemates who went onto roles at engineering companies did use more of what they learnt.
