First, learning efficiency is improved. One-on-one tutoring means that teachers and students are teaching at a closer distance, and teachers only teach students, so this teaching method is more direct. Under this more direct teaching method, the efficiency of teaching and students' learning is much higher than that of class teaching system.

Second, students' attention will be more focused. Because it is difficult for students to think in close distance teaching, and teachers will not let students miss classes, students are very efficient in attending classes.

Third, a higher level of counseling. As a one-to-one tutor, the teacher's teaching level and teaching experience have been certified by the counseling institution and have high teaching ability, so students can receive higher-level counseling.

Fourth, the teaching efficiency is higher. Only when teachers have a good teaching level can students have good learning efficiency. Then, under the joint action of these factors, the tutor's teaching efficiency is higher.

Fifth, time is more effective. Students' study time is limited. If they can improve their study efficiency in an effective time, then their time utilization is effective, scientific and valuable.
