I had a similar situation where I accelerated various subjects for years e.g. General Maths and Psych in Year 10.
Honestly, no it’s not hugely important whether you have friends or not in the class. The real benefit of having friends in a class is that you have someone on the same bandwagon as you, so it’s more enjoyable that way. (There’s also a benefit in
not having friends in the same class as that can be distracting sometimes.)
Even if I had friends would I be given any class time to communicate with them?
Probably not, unless it’s group work and you’re working with them. It’s pretty much very similar to having mates in your class in high school.
P.S. This is a pretty normal situation for uni students to be in where some students are a year older (or more) or every class has people you’ve never met before. In a way, you can think of this situation as practise.
