1. Clear requirements: First, you need to be clear about what you need to modify. This may include grammatical errors, spelling mistakes, unclear expression, structural problems, etc. You also need to be clear about how you want to modify these contents.
2. Make an appointment in advance: If possible, it is best to make an appointment in advance and have face-to-face communication with the tutor. This will give you enough time to prepare your request and your tutor enough time to consider your request.
3. Respect and courtesy: When you ask your tutor, you need respect and courtesy. You should avoid showing impatience or anger in your email. On the contrary, you should show respect for your tutors and appreciate their professional knowledge.
4. Provide detailed reasons: When making a request, you need to provide detailed reasons. For example, you can explain why you think something needs to be revised and how you think it should be revised. This will help tutors better understand your point of view and make it easier for them to accept your requirements.
5. Show your efforts: If you have tried to revise your paper by yourself, but failed, then you should tell your tutor what efforts you have made. This will let your tutor know that you are serious about this problem, and it will also make them have higher expectations for you.
6. Seek feedback: Finally, you should ask your tutor to give you feedback. This will help you understand whether your paper really needs to be revised and how you should revise it.
