Colleges in Navi Mumbai

If you are from general category, then you have to score at least 50% in PCM group to get admission in any engineering college. I think you disqualify from the criteria. I am sorry to say but you are not eligible for engineering. There might be chances to qualify for engineering if you belong from SC/OBC or any other reserved category, as the percentage required for this category is 45%.
Best of luck for your future.
