Actually...

When I am having my lesuire time, I think my past. the most thing I thought is regarding some tests. as for now, I have gotten many tests in my life, but I have not satisfied with my score. and then, I am living with many regrets, such as dealing with my time. but I know the most useless time is regreting about past. So I try to don't regret my doing.

Hello there!

Thanks for posting your composition!

It\'s really useless to think about what you have done in the past.

What you do should  is learn from them and move on with your life.

Don\'t dwell on things too much on them:)
