Everyone who tells you income doesn't mattwr is lying to you. Income does matter in Durham university. Especially when it comes to the social part. The university itself doesn't discriminate, and neither will your fellow students. Everyone will be accepting, but you can expect during your first few weeks a lot of "so what school you're from... Oh never heard of it" 'Cause its probably not a private school.
The reason money matters is because many of the kids will have buttomless wallets, daddies money to spent on a night out every night. Don't feel compelled to have to keep up. The worst part is often the high barrier to social events costs. My college and i **** you not charged me £240 for a pair of tickets our college ball. Then i had to get a tuxedo and spent a ton of cash for drinks until the sun rises. That night was worth the cost of one month rent for slme people. Its worse for girls who are encouraged to get a dress for every ball they'll attend.
It's of course al consentual, but yeah if you want to be part of all the fun then either have well off parents or chose the plenty of free options. Skip balls but come to socials at the library instead. No weekend away but a night at fabios will do.
Its not that bad tho you'll still enjoy yourself
Good luck
Before i forget this was just the social part, university lessons cost money as well. Books are freaking experience. Check your reading list and the prices of each book. It can easily accumulate to £300 depending on your modules
