If you are a tutor in your class, it won't have much influence on you. If you mean the tutor of your thesis, you'd better find a serious and responsible person, so that you can supervise you to finish your thesis on time and know the shortcomings of your thesis, so that your thesis defense will be fully prepared and easier. To put it bluntly, find a strict teacher, not a respected teacher, not a good relationship, but a more responsible teacher for many years.
