Many congratulations on being accepted to study medicine. You are clearly very academically able to complete the course, otherwise you would not have been accepted. Any change of environment can be unsettling, and many people take time to settle in to the new university environment. The key thing is to establish a routine (once the course starts after freshers) and hopefully you will find that easier. Medicine is unlike many other courses, and the study time required is far greater. Plan your week around your lectures, and make sure that you have some time set aside for yourself too, whether that be clubs, hobbies or nights out with friends. You will find that most people will be anxious about starting university, so you won't be alone. Have a great time, and best of luck with your studies.
