Go for graduation from Delhi University. Admissions are based on class XII merit.

Diploma is not compulsory for doing B.Tech. 12th science along with JEE Mains is compulsory for doing B.Tech.

As per the information available on the web, I got to know that JEE Mains paper 2 results are releasing on 27th May 2017 and AAT results will be out on 18-19 June while the exam for AAT is going to be conducted on 14th June.

Best career option for student with computer science is to B.Tech CSE or B.Tech IT because these degrees are the most accepted graduation degrees to become a software engineer. Students with Computer Science in 12th board has a relatively advantage over non CS students during initial 2 to 3 semesters of B.Tech CS and B.Tech IT.

You are advised to appear for NDA exam conducted by UPSC to become a Commissioned Officer in Armed Forces. Your all education expenses including boarding & Lodging will be borne by Government of India. It is an excellent career option.
