Hello, I'm one of the student ambassadors here at Coventry University.
As started above, I'd always recommend having a laptop with you, especially if you are a full time student.. This is because not only would it be beneficial to allow you do catch up on assignments on the go, some seminars/lectures require you to have your laptop with you, whether it being to read a study, or fill out some paperwork online in order to get the most out of your studies, I'd recommend you having a laptop to ensure that you don't get caught out, it's always better to be safe than sorry..
However this is all down to personal preference and if you believe you'd be able to be without a laptop, that is a decision that is down to you and you alone-
I hope this helps.
Kind regards
Courtney H
