Hi,
It's ok if you have not cleared 11th class with good marks because the eligibility criteria for JEE demands a minimum 75% marks in 12th class. So if you study hard in your 12th class and get a score of anything above 75% then you can surely attempt for JEE exams.
I hope I am clear
I wish you best of luck
Thank You
