What are you going to be studying? I can't give you any specific advice, just that it's very different from high school! 
Even though I have fewer classes and subjects than in high school it doesn't leave me as much free time as I thought it would. You are going to learn things in detail in a relatively short period of time, so it's very important to study what you really enjoy. Otherwise, it's just going to be a pain. Don't worry too much about the grades, be happy when you just pass (but still do your best!).  I guess that would be kind of a mental preparation
I don't know about the accommodation because I attend the uni in my hometown so I just live at home. But from what I've heard from my colleagues, renting a flat gives you more privacy and freedom, but halls are usually a lot more affordable and better choice if you are really sociable.

She is so cute, like a Japanese version of Munchy The sushis and colour combo look really nice.

Very pretty! I think I like Fluttershy the most

I like the New York accent (or is it called Brooklyn?). I also like British/Irish accents and I would like to speak English with the BBC accent And English with German accent is just I don't like English accent from my region because it sounds like Russian but way duller. I do love when foreigners speak Croatian though!

Definitely G3 winter Minty with pink gradients on hooves 

I'd personally like to see BigMac, Granny smith, Roseluck, Coco Pommel, Fleur de Lis and Honeybelle (BB pony) And Cloudchaser and Flitter!

I have the crystal empire version. She has really nice colour combo and beautiful eyes
