We do learn from our experiences when we look back, ponder upon them. It's good that you reflect upon why you were in that school and did better, congratulations :)
Meanwhile, the mistake you did on the second story is quite understandable. The good thing is that you realized it before it brought more damages :)

I hurt that person and and he may not forgive me for it. I really feel guilty to whenever I remember about it. I hope someday I will get the opportunity to apologize and I will try to convince him why I made the mistake.
Hope you'll get the opportunity to apologize. But he might have forgotten about it already so don't be too hard on yourself hehe.
I just hope that for it .
