On the topic of laptops, is there enough space in lectures for a 15.6" laptop and mouse space? lol my touchpad doesnt work :p
Definitely not lol.
Screens larger than 13" are really for home use only, a laptop with that screen size is going to be a pain to use at uni
Yes, definitely. I remember having to bring my 15.6" laptop to uni because that was the only laptop I had. Boy, can I tell you that it was a very, very, very bad idea.
On the topic of bags, if you don't have many lecture notes (ie. not maths subjects or arts subjects with readers), then a satchel should be fine if you're a satchel person. But other than that, if you carry around a shoulder bag, that's perfectly normal.
