I got only 32 percentile in jee mains. I m very disappointed as I have expected far better score than this. Where do I stand? What tips should I follow to get decent score in next attempt?

It was quite unfortunate that you scored 32 percentile and didn't qualified JEE Mains. But don't worry you still have chance..the April Attempt..Start studying with all the potential you have..Stop procrastinating if that has been a great problem for you..You have got enough time untill the next Attempt so you can prepare well in this time. Try to clear your concepts and solve as much questions as possible..Don't go for covering the entire syllabus...but rather focus on strengthening whatever you can. Because the level of questions is really good and they aren't that tough but you really need to have a proper knowledge about the concepts. Also solving Previous year papers are really helpful because they give you a brief idea about what type of questions can be asked in the Main exam and you can practice well. Also you should join a good online test series because evaluation is also important..only studying isn't enough... knowing about what are your strengths and weaknesses is also important...and you need to be really honest with yourself...don't have a doubt on yourself..if you know a concept then be clear with it....even if you have 1% doubt then first clear it...because we don't know from where the question might come....so better to avoid having a blind spot...It's not that tough to clear JEE Mains but you need a good amount of focus and determination...as required in every aspect of life...so just treat it as a part/challenge of life which you have opted to clear....If you will do this with full of heart then no one can stop you from clearing anything in life...and the Exam as well..
Thank you
