Well done by the way
, you'll have an amazing time here.
Although the first 2 years don't count you should still put some effort in because it'll pay off later. One of the first lecturers you should come across is Martin Reekie who is an absolute legend. If you ever have any technical trouble he's a good place to go - if he's your DoS (Director of Studies) you're very lucky!
Not sure what I can say about lectures and coursework except try and keep on top of it all. It's a good idea to write everything down, some of it might go in! I tend to re-write and think through everything before exams which helps. Don't be embarassed to ask questions in lectures since if you're wondering about something the chances are everyone else is.
During first semester you'll get to pick three out of the four engineering disciplines to take lectures in (Electrical, Mechanical, Civil and Chemical). It's a good chance to find out about the other fields and discover if you'd like to switch from EEE - bad idea to but I'm slightly biased!
In terms of outside subjects that's up to you, in principle as long as it timetables you're fine. In first year all of the lectures should be around George Square so you shouldn't need to worry about where to go. If you intend to take outside courses in second year this might be more difficult but generally most engineers stick to their prescribed finance/management related modules.
I chose Physics as an outside course into the first half of second year and dodged one of the management modules. Physics turned out to be very useful and I didn't miss much! I would recommend it, but it is NOT the easy option. A lot of engineers picked computing courses which aren't challenging, but they're not of much use later. Doing Physics gave me an advantage in 3rd/4th year Electromagnetics and Radio Frequency courses.
Good luck with the packing but most importantly get out and meet people during Fresher's Week! It's really intense but you'll make some great friends and everyone's in the same boat
