I am in final year and my percentage is 53.3 but now I am focused towards my carrer in construction field what should I do.nickmar? Or rics?

NICMAR is way better than RICS. Honestly speaking though, the companies that come here generally require 65 percent and above all throughout the career.

Your percentage doesnt matter if you do get into post graduation. Many companies do not give any such criteria. Both colleges are good enough.
