Is CEED based upon the parentage of B.tech or not? B.tech need all clear or not

You should have b.tech cleared with 55% (ST : 50%) or more.

Dear Manish,

As per the eligibility criteria of CEED, aspiring candidates should have passed a degree/diploma/postgraduate degree of 4 years or 3+2 years (after 10+2 level). Candidates who are in any of these qualifying exams in the same year (by July of the same year) as that of the application form and exam of CEED are also eligible to apply.

So, to apply and appear in CEED, either you should have passed B.Tech or should be appearing in the final year of B.Tech. You should pass B.Tech, but there is no minimum marks requirement to appear in CEED.
