Come to the classroom earlier than other students and choose a seat near the podium. When sitting in the front row, the teacher's voice, handwriting on the blackboard and courseware on the electronic whiteboard will be clearer, and at the same time, the interaction with the teacher will be enhanced, which greatly improves the efficiency of listening to lectures.
Take notes carefully, sketch down the key points the teacher said, and record them. You can annotate what you think is important and what is easy to make mistakes. If the teacher speaks too fast to remember, take a picture of the current content with his mobile phone in time, and then complete the notes according to the photos afterwards.
Don't stay up the day before class, a good mental state is very important, and the energetic thinking speed will be accelerated.
The above is my opinion, I hope it will help you, thank you.
