1. Your student loan may seem like a lot of money, but the first three weeks of surviving on it will leave you in tears, scouring the reduced section, and counting down the days until the next instalment.
2. No matter how many people 'don't do the reading' and manage to still get firsts, you'll still be that one person that tries really hard and comes out with lower grades. It sucks, but you'll always be that one person that has to work ridiculously hard to keep up.
3. You'll get told a million times that first year doesn't count but it still won't stop you putting your all into it - because it matters. The grades might not go towards your final grade, but it is such a steep learning curve that you'd be daft to write it off.
4. That over the three years, you'll cry more than you've ever done before. Why? Because everything just seems more intense. You're either ridiculously home-sick, or delirious from too much alcohol and lack of sleep. Either way, you'll blub. A lot.
5. Eating healthily and exercising might not seem like a 'cool' student-y thing to do, but you'll ultimately feel a whole lot better when you're full of protein and vegetables rather than saturated fat and salt. You might not realise this until you put on about two stone and feel crap in your second year, but you'll make it your sole aim in third year to be good at least 50% of the time...
6. You'll get a second wind in third year that makes you want to drink more, party harder and give it everything just because you know the amount of time that you can ignore the real world and live in student-land is quickly slipping out of your fingers.
7. You don't have to love the people you share halls with. I knew that I was going to live with Matt so it didn't bug me too much, but some of my friends didn't get on too well with theirs and they spent the next few years happily bunked up with some other people that they met.
8. You'll become a better person. Not because you 'increase the intellectual boundaries' or anything as pretentious as that, but just because you'll realise what you're capable of, and you'll care a whole lot less of what people think about you.
9. You'll make some friends for life, but just like those you knew in school, a lot of them will fall by the wayside, engage you in childish arguments, and essentially drain you. You'll just get better at picking out the valuable friends and identifying the time wasters.
10. University is an experience like no other. You're thrown into a situation where you have a ridiculous workload, unlimited opportunities to drink and go out, a huge mix of people to meet and a tiny budget to do it all on. In the end, you'll be glad that you've immersed yourself in that world, but you'll be ready to move on and see what your future has in store for you.
