University Of Calcutta — Examination issue for Sem VI

Many students are not able to give Sem6 exam I request the authority to allow them to sit in exam as if not it destroys 1 year of students carrier.
Circular allows us to sit in exam but CU claims that students can't sit in exam if the don't sit for there previous sem.
But I have cleared all the semester and same with the rest of the students still they aren't allowed to sit in the exam.
Pls provide and immediate solution to this
