Don't have or haven't? I don´t know when I should use one or the other

My Homework . Could someone help me? I've just finished my homework because the wednesday I have English class. I'm learning English since November 2010. My teacher is from US. She is living in Buenos Aires since a couple years or a little more. She is learning Spanish with a teacher as well. Now, She speaks Spanish better than me English. I want to improve my speaking. I feel that I'm writing, reading and understanding better than speaking.

Please you help me! Anyone corrected me "My Homework"

What is the difference between "Should" and "Shall"?

But I miss them too much so I bought a ticket and I'll go to Jujuy a week in November. I'm waiting that come that day

Last Tuesday went to my tennis class Last Tuesday the wheather was very cold and cloudy. I woke up without want to go to the tennis class but finally I went there. My class is at 12. Until that time my couch had been unable to give any class because other people had missed to their classes. So my coach had all the energy... My God! How did I run!
