Hi Pranay,

First I would like to say its absolutely alright if you are not feeling confident enough as for now for your boards but just because you are having this feeling taking a leap through the entire year again shouldn't be in your mind right now as you have ample amount of time even if you start working towards it right this moment dedicatedly with full enthusiasm and I can assure you if you start from today itself you will come out of your exam with flying colors. Make sure you follow right strategy and do your work dedicatedly and you work under someone's guidance. Timely you also need to keep asking your doubts so as to make the concept more clear. You should also keep one day in the week for  revision as we know the syllabus is vast and to remember it till boards it will become volatile so we need to brush it up regularly. Stay positive and work towards your goal now. Its never too late to start.

Hope my answer helps.

See if you lack confident doesn't always mean that you should drop it. You have to check the reality of your preparation. Is your preparation good and you are still under confident or if your preparation is bad and you are underconfident. This are two cases you should ask yourself and based on that you should take the decision. Now this can be a hedious task for you but to know about your preparation it would be better if you can give some mock examination. This will really give you the scenario in which you belong and also will increase the confidence. See time is precious, so if you see that you can still manage to score good in boards then don't take drop. If you really think that are no way available for you then I would recommend you take a drop only else try not to take a drop because time is a valuable resource.
