Dear aspirant,
As you have mentioned that you have secured 42k rank in JEE mains and taking into consideration that you belong general category and you are aiming for dtu and nsit so let me tell you that the cut offs are way higher for outside Delhi candidates.
Although various factors are considered while deciding the cut offs like number of candidates appearing in the examination, number of vacant seats in college, previous years cut offs and difficulty level of the paper.
