According to the National Standards for Students' Physical Fitness and Health, the scoring standard for pull-ups in the senior high school entrance examination is 10, that is, full marks.

The most effective and convenient thing is to do push-ups. Just do it every day in your spare time at home. If you can do it for a month every day, there will be obvious improvement.

Use the fitness equipment in the community, hang more horizontal bars and try to pull them up.

Bend and stretch your arms repeatedly on the parallel bars, lift them up and then press them down and support them repeatedly.

There are ladders in schools and many communities, and you can climb them to practice.
