Hello,

If you have cleared Jee mains you are eligible for Jee advanced. So you can appear for Jee advanced but after in your advance result after appearing you wouldn't be able to see the results because to qualify ,the criteria is 75% in boards. So if you want to give advance and if you have cleared mains you are free to apply for Jee advance but due to 72% you wouldn't qualify Jee advanced.

Best wishes for future
