challenges of living in Britain

I think the biggest challenge of living in Britain is culture shock. The Uk and China have a big cultural difference. In China, teachers will tell students the key point of examination. So I do not need too much time to study by myself. If I follow teachers, I can pass the examination easily. But in British, I Will have much more time to plan by myself. If I not Know how to study by myself and take active in group cooperation. I may have trouble in passing the examination. But I will try my best to do everything, overcome this challenge and adapt to the new environment soon,
