Hello,
Things you can opt for:
1)First, the student should find out the interest area of him by analyzing himself.
2)Self study is much important.
3)Failing in examination is really not the matter of your, it is the matter of the reason. All are created equal by God. Failures are the stepping stones to success.
4)Analyze what happened during your exam preparation and exam writing.
My suggestions:
1)I would suggest you to prepare for next year's examination.
2)Prepare well for the exam.
3)While preparing for exam, you can opt for online/ offline part time job.
4)Study/understand the matter of the subject in depth.
5)Doing jobs is just my suggestion, so that your parents get more belief in you and you will be more matured. This is only my suggestion.

Good luck friend. You can do it. Thank you.
