Hello aspirant!!

First of all don't get disheartened by getting low marks as your class 10 % matters little in your career and now if you are in class 11 ya 12 then I would advice you to study sincerely as hardwork matters.If you are going to take JEE coaching then it is also good option as it might helps you to fetch seat in IIT or nit so  work hard and this present time don't think of job in mncs as if you have ability then you will definitely get a job .

Good luck!!
