Dear student,

In jee advanced or IIT-JEE you are allowed to give exam only upto a maximum if two attempts. And your first attempt is counted as over in passing year of class 12th. And second attempt will be over in the next consecutive year of your class 12th passing year. Whether you give the exam or not, your attempts will be counted as over.

So, now, if you think that after class 12th you will again study in class 10th, then first of all you cannot give jee mains nor jee advanced. Because in jee mains you have a maximum of there attempts allowed in consecutive year counted from your class 12th passing year.

And if you do this type of thing, then your age will also be increased, and you cannot also give other competitive exams.
