Sucess in exams last try

I need you help St Jude. Please help me understand and pass my operations management and microeconomics exams in July. This is my final try and in order to continue with my studies in this University I must pass these exams. May I get the questions that I know and can answer. I study so hard for this and want it so much for myself and to make my parents who have not had good things happen to them in a long time happy.
