Hi buddy with this rank you cannot get a seat in DTU.

No, if you have a Diploma degree, then it could be possible. But, there is no medium to get admission directly in 2nd year of B.Sc. IT after one year gap after class 12th.

Yes, you can apply.

Check out the complete list of courses for MA through distance mode offered by IGNOU on July session.
For your enquiry, let me tell you that admission of various courses through distance mode is last on 15th July.

Engineering cut off will be considered. Maths -100 + physics 50 + chemistry 50.

Two things, one the answer by Partha - tough to shift from commerce to Science. So, probably an MBA or an MS in Finance are options, but not MS in the Science stream. Second, US typically requires a 4 year UG education. B.Com is only for three years, and so 1 year M.Com may be needed.

If your aim is to join civil services, then B.A. will be best for you. You will get the UG degree in a short span of 3 years, and then you can appear for the exam. Going for an engineering degree is not suggested, because it will take 4 years and in most cases a year of drop after class 12th is required. Just join Government College, it is better to go for any 3 year UG course and prepare for UPSC with full power. I will suggest you to go for B.A. .
