Hi Aman,

As you mentioned that you have studied nothing, but during the online classes of school or your coaching/tuition(if any) you must have gone through some topics, chapters etc. Do not lose hope. Ask for guidance to your school teacher or tuition teacher, they will surely help you with your problem. Also, start studying as exams are near. Cover the topics first which are important (you can ask about this from your school teacher). You can also get some important notes from your friends.

Hope it helps to boost your confidence, thankyou!
