Hello aspirant,
Only those candidates who have passed the secondary school examination of Cbse board ,will be eligible to appear for improvement exams. For giving jee again, you need to give improvement exam as per the rules which state that. If a candidate has passed class 12 in say 2017 and wishes to improve his aggregate marks in 2018 to meet the requirements of 75% he/she can reappear for any number of subjects he wishes for improvement. The percentage of marks will be considered for the year in which candidate scored the highest marks.
So u can give improvement in your desired subjects
Hope it helps.
