I failed my exams and I don't know what to do.
Did you not properly do your schoolwork before the exams?
I did not do my school work, I used to be very smart and I did not have to do any homework before, so I'm not used to it.
Sometimes studying for the exams can be very tiring and boring, I feel that. But your performance on this exam will be recorded in your transcript, and that transcript will help you find jobs in the future, so I would recommend that you study very hard in your other exams in the future so that you would get a better job that you would apply for in the future.
What's the point, school is just temporary and I really just want to get a job. But I'll try hard to study in the next one.
I think that's a good plan. Once you get in the habit of studying for exams college will be a so much easier for you.
