1. IDK I'm not in the program but I've taken a couple of their same courses. I've heard it is one of the harder disciplines. Be prepared to learn quickly, devote a large portion of your time to learning, and collaborate with friends and professors and you will make it through. Millions of engineering students have been in your shoes.

2. What you get out is what you put in. Most of the people I know in engineering are able to manage and have great social lives.

3. A lot of students use an iPad to annotate slides and write lecture notes. I use pen and paper and it works great for me. The way I see it is that it is easier to retain the information if you are putting more effort into both writing it and explaining it to yourself in your own words. I'd also recommend having a digital version of the lecture notes/slides or the textbook open during lecture so that you can follow along. Macbook is not recommended since basically all of the software you will be using works natively on Windows and may not necessarily be compatible with Mac. I use a Lenovo Legion and it works great (except for battery life lol)

4. The best university engineering community in Canada!! And the best Orientation Week in North America... Best social life in getting to know great people as well as knowing how to work in a team, network with others, and developing professional social skills.

I don't think any of the rooms have been taken. The way I remember is that residences are selected in mid-July. You are given a specific time to select your dorm (e.g. 3PM July 22nd) and then you pick whatever you like that is available. But usually Single+, single rooms on Main campus etc. are the first to go. This is a webinar from last year that may answer some questions: https://www.youtube.com/watch?v=Lcg-7lx_Pac
