Maths Spl

You are eligible to seek admission in MBA IT if you had above 50% marks in graduation degree. With MBA IT degree you can get job in IT and ITES companies in Pre-Sales support and BA roles in campus placement. With experience you can grow into Sales Marketing, Project Management and Account Management roles.

Yes, you can surely get admission in DU.

Since you have got 50 marks in maths you must take the improvement exams to eradicate any job oriented problem or any related stuff in future. You must secure a minimum of 60% in each subject.

After completing BE in civil engineering, M.Sc. in mathematics is not recommended. You should go for either M.Tech or MBA. You may do your M.Tech part time.

My advice is not to take any reference book before completing NCERT since 90% questions are asked from this book only, after that you should go for XAM, IDEA or Arihant.

To crack IITs you should have full command on NCERT books. You can also refer RD Sharma, Arihant and RS Agarwal.
