The eligibility depends on the type of course that you wish to pursue, the details of some courses is stated below:

Bachelors Degree: Class 10+2 examination with at least 50% marks.
Post-graduation degree: Bachelors degree from a recognised university with at least 45% marks.
Graduate & PG programs may also require you to appear in entrance exams such as NCHMCT, AIMA UGAT, E-CHAT etc.

Yes, why not, this is absolutely possible.

According to me, Polytechnic is the best way for you as it will be a technical field that will have lots of job opportunities so you can choose Polytechnic.

You can do full-time Diploma in Engineering along with class 12th board in private mode. It will require extra effort and if you have the will to do both simultaneously without impacting your academic performance in both the courses, you may go ahead.

Hello,
Your query is a little difficult to understand. One does not require polytechnic to complete 12th. In fact after 10th you can go to a polytechnic to pursue skill based training. You have to go to a normal college for doing 12th.

Hello Raj,
Admissions in polytechnics are invariably controlled by the concerned DTEs of Tech-Edu of the state. Normally, states conduct entrance exam based on your rank and you can get the branch that you desire.

Yes, you can fill the form for polytechnic.

Polytechnic are institutes in India to provide entry level education below graduation degree in the field of engineering, technology, Applied Science, natural sciences and other fields. For example Polytechnics in India offer 3 years Diploma in Engineering branches after 10th class. It is a skill based educational qualification which has more practical training. Diploma-holders of Engineering are able to get jobs in supervisory level jobs in manufacturing and services industry.
