£87.50 per week seems a little much if you're in catered. Do you get 19 meals a week or 14? If you have 19, then you only need about £10 a week for weekend dinners. What kind of books are you into? Amazon offers a 5% discount to students if you have an NUS extra card, and other bookstores and shops will definitely offer discounts for students. Unless you're going to be buying games and videos
every week £88 seems like you're overdoing it.
The cost for societies depends on the societies you join. If you want to join 7, I'm assuming it's because you have certain societies in mind. My advice to you would be to check their meeting times to be sure you haven't double, triple or even quadruple booked yourself.
Do you have your own phone? Or do you want to get a new one here? In the UK you have the option of having a contract (where you pay a set amount each month to your provider for a set number of minutes, texts and a specified data bundle) or there is a 'pay as go' option, where you are able to 'top up' your credit when you like. With the contract option you can typically get a phone with it. Contracts range from like £10 and up, depending on the phone. To put it into perspective, an iPhone 4 8GB starts from about £18 a month for a 18/24/36 month contract. If you already have an unlocked phone then you can always just get a sim. Sims are typically free when you buy £10 airtime.
As for other fees, there is the cost of an academic gown, which is about £80 - £138 depending on whether you buy secondhand or new. As well as, textbooks.Textbooks can be expensive! I recommend waiting until you get to St Andrews where you will confirm your modules; however, if you applied to study, for example biology, then there are modules that you simply
have to take and you can find the reading list for those books on the library website (
http://resourcelists.st-andrews.ac.uk/index.html). If I were you, I would only buy required texts, secondary reading I'd borrow from the library when needed. What course are you doing? If your doing biology and chemistry you are going to pay lab fees. If you're like me, doing geology (or maybe another geoscience), you have to factor in the cost of field trips (£700!). As I'm British, I can't actually tell you about the police registration fee--I simply don't know--but maybe you could search on-line or ask other international students?
