<human>: Can you give me a shortened version of the text?

As I explained in a thread just a moment ago, my Maths teacher while in school I didn't really like. She was very strict and not pleasant to look at, as a teenager this was a good reason to dislike someone. She also seemed to have a problem when I corrected her mistakes on the board, I wasn't smarter than her obviously but all teachers make mistakes and I'm sure it's best for the class if they get fixed.

Anyways, when it came to coursework I was lazy, my time out of school was more importantly used hanging with friends and trying to get with chicks... but coursework needed to be done, it was 25 - 50% of your final grade depending on the subject. 

When I was a day away from deadline my Maths teacher actually stayed at the school until 7pm (School closed at 3:25) giving me 1 on 1 help with my coursework, that moment really made me see her in a new light.

After my exams were finished and I  went to the school to pick up my results, I had the intention of opening them with my mother but with my Maths teacher there asking what I got I couldn't resist. I opened them and saw I got an A, she was almost as happy as I was. Without her I never would have got that A, and I made her aware of that too.
<bot>: A teacher I hated stayed at school on her own  time helping me complete my coursework, I got an A.
