Thank you for writing here. Board exams are a tough and very stressful time for every student. It is normal to be feeling anxious and underprepared. As much as tutions and coaching classes claim to help in preparing one for exams, not everyone is benefited by it.
I understand how overwhelmed you must be feeling, but it is important to be calm and look forward to what can be done best in the current situation. Since your exam is tomorrow, there is still some time left to prepare a few topics, which you feel are important and will appear in examination tomorrow.
Going through previous question papers' can help you identify what type of questions are most repeated and will help you prepare accordingly. You can prepare yourself on topics where you can score marks easily.
Nobody deserves to end their lives just because they did not prepare well for an examination. Every dream and aspiration must be worked hard and fulfilled. Don't let societies expectations and judgment stop you from doing and being your best.
Every parent wants and wishes for their child to be happy and healthy. You have already told your parents that you are feeling underprepared for the exam, and they have accepted it, and have even asked you to do well in compartments if you do fail in the boards. Take this as another chance to prove yourself and work hard towards it.
Take a deep calming breath, and do the best you can in the current situation. Please do feel free to reach out to us on our chats for the one-to-one session if you feel the need to.
