Learning goal for this year in LA

I want to understand the litirature book ' To Kill A Mocking Bird ' better by the end of this year. Its a top selling book and i feel there are alot of things and morals to learn from this book if i understand it weel enough. I also would like to improve my Short Story aas it was the component which pulled my grade down by alot. The other section of LA which i am not confident of is Summary. It has no standard answer like Math and no one knows which point should we write down. It wort of depends alot on luck to me. Even though I did well in it last year, I hope i will be able to grasp the key to getting the main points everytime without doubt.
