A draft, first change RMB into pounds and then make a draft. It is convenient for you to take money, passport, etc. to the bank.
You don't need much cash. First, you can directly ask them to transfer the money in the draft to the card after you arrive in England. This process (including card collection and money exchange) takes about a week. Secondly, when you first arrive in England, you won't be asked to pay for the dormitory at once. At that time, our school didn't send the payment letter until you lived in 1 week, and then asked us to pay it the next week. There is a one-month buffer period for tuition fees, so even if the bank is slow, you don't have to worry. Just tell the school.
So as long as you don't start shopping as soon as you get there, you don't need to bring much cash. 1000 is enough for you to buy some daily necessities, eat, drink and be merry until you get your bank card.
By the way, I didn't even bring cash when I went. My mother thinks that Britain is the European Union and will support the euro, so I just have some euros on hand, so let me bring them = = ||| But there is an exchange counter as soon as the airport comes out, which is not bad ~
