Hey, Bishmitra!

You are not eligible for CEE Assam 2019 as the brochure for the exam clearly mentions that " the candidate must pass the Qualifying Examination individually in the same sitting without any grace marks in the subject of Physics, Chemistry, Mathematics and English". For more information regarding the examination and it's eligibility criteria, refer to the following link: http://43.240.64.221/astu_cee/Pdf/IB.pdf

Hope this helps. Good luck!
