No Praval, you cannot apply for CLAT exam this year as you will not have completed your 12th board exams in 2020.
According to the notification you need to have passed your Senior Secondary School Exam/ 12th Board Examination for applying. But by the time the CLAT results will be out and admission starts, you will be in class 12th and would not have completed your 12th boards.
So you need to wait for another year and give CLAT exam in 2021. Also, please note that you must have a minimum of 45% marks in your board exams for being eligible for the course. SC and ST candidate need 40% marks.
