Don't bring more luggage than you can easily carry yourself. Bringing too much luggage (more than one large suitcase or two smaller ones) means you won't fit on the University coach. Even if you're travelling to Plymouth independently, it'll be difficult if you can't lift all your belongings on your own.
We strongly advise you bring a credit or pre-paid card that works in the UK in case there are delays in opening a bank account. Bring enough money to cover your immediate needs on your arrival in the UK, including customs charges, rail fares and any emergency expenses. Remember that you will probably have to pay a deposit for your accommodation before you move in. This is normally the equivalent of one month’s rent but it can be substantially more, depending on the type of accommodation you are renting. You need to ensure that you have sufficient funds immediately available to cover this. Remember it can take two to three weeks to set up a bank account, so bring enough money to support yourself until then.
The weather in the south-west of England is fairly mild compared to other parts of the UK but changes quickly and often. It rains often, particularly in coastal locations, but we rarely experience extreme temperatures. The winter can feel quite cold, and occasionally there is snow. The summer is usually warmer (although it still rains!). Bring warm waterproof clothing, including a raincoat/jacket, umbrella and possibly waterproof footwear for the winter. Or you can easily buy these at a reasonable price once you've arrived.
