Can I send it again if the tutor doesn't reply?

The specific analysis of the specific situation mainly depends on what mentor you are looking for. The specific analysis is as follows, for reference only, I hope it will help you!

First, there is something very urgent.

In this case, you can send a message to your tutor in advance, which will give you some time to wait for your tutor's reply. In short, you can't wait until the last minute to send a message. If your tutor doesn't reply to you, you are also in a hurry. I sent it in advance, and the tutor won't reply to you. If it is particularly urgent, I can send it again. If my tutor hasn't replied, you can consider calling my tutor. After all, it is important to deal with urgent matters.

Second, it is not particularly urgent.

Also say hello to the tutor in advance, and give the tutor a period of time to respond. You have plenty of time to wait for a reply. If you communicate with your tutor through WeChat or information, personally, you don't need to send it a second time. You can send something else, for example, ask your tutor if he has time, try water, and see if your news is heavy because there are too many messages from your tutor. If it is an email, you can consider sending it again. Maybe the tutor didn't see it!

The above is for reference only. The specific analysis mainly depends on how you usually get along with your tutor.
