End of School and Beginning and end of Summer

At my school my graduation is in about 25 days, well not for me but anyway what I want to do is get good grades for the last quarter.  I have not done well for the last 3 quarters but I want to finally try on the last quarter.  Kind of dumb to try on the last quarter but that is my fault.  I want to get A's and B's and at least 2 C's.  I am expected to stay after school ends because of my grades so i guess I am going to summer school.  I did not do good so after summer school I will receive my diploma.  It's disappointing but again it's only my fault.  So anyway that's basically my Summer.  I hope you did good on your grades.
