I took the exam on Feb 2015 & got 88 marks (due to 5% concession I got the eligibility certificate).

If I retake the exam (in Sep 2015 or Feb 2016) & if the marks got reduced (say 70 marks), can I still use the eligibility certificate I got for Feb 2015?

In ctet.nic.in I see that we can re-take exams, but it didn't mention what happens in above scenario.

Can someone please share your thoughts on the same.
