Hello Jayant. Central Universities Common Entrance Test (CUCET) is an all-India level entrance exam conducted jointly by 14 central universities for admission in UG, PG, and PhD courses offered in all the participating institutions. Note: Apart from central universities, Dr B R Ambedkar School of Economics (BASE) is also a participating institute for the exam. Central University of Rajasthan is the coordinating university for the exam, which invites applications from eligible students each year.

And it doesn't work like that. You can give the exam once and that result will be only considered. You cannot give 2 attempts at the same time.
