Polytechnic

The college which you will get depends on the percentage you got in 10th standard. There are no engineering or Diploma colleges in Chintapalle. To pursue Polytechnic, you have to go to Vishakhapatnam. Vishakhapatnam have good polytechnic colleges. There is also a Government Polytechnic in Vishakhapatnam.

You have to qualify the entrance exam of polytechnic colleges where you can want to get the admission, all state having their separate exam for polytechnic, you can visit online form for that.

The eligibility depends on the type of course that you wish to pursue, the details of some courses is stated below:
Diploma Class 10th pass from a recognised board with minimum 40% marks.
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.
