Hello Priyanshu bora,
Polytechnic admissions usually start after Class 10 results are declared. In most states, the admission process begins between May and July every year. You will need to apply through your state’s polytechnic entrance exam or counselling portal. Keep checking the official state board or technical education website for notification. You should also stay in touch with nearby polytechnic colleges so that you don’t miss the admission dates.
I hope this helps you.
