Hey Abhinav,

For preparing the rank list of JEE Main 2018 Paper 2, class 12th marks will not be considered for normalization. The inclusion of class 12th marks for normalisation has been scrapped from the year 2017.

Min. Requirement - B.Arch/ B.Planning Admissions: Candidates are required to have mathematics as compulsory subject along with 50% marks in total including five subjects in addition to qualifying in JEE Main Paper 2.

So you should give both exams. As, preparation strategy and syllabi is almost same.

All the best!
