Maths

Maths is the most irritating and hardest subject, I have studied before but my mother had ordered me to score 100 out of 100 and I am helpless after this order. I really don't want my mother to be sad. My mother had also said me that I am capable to achieve that marks. I had good hopes to make my mother happy, just for that I want a perfect solution to score 100 out of 100.Please tell me any solution for that.
