To be eligible to get admission for pursuing Polytechnic Diploma course, you must have completed 10th standard with minimum aggregate of 35% marks from a recognised board. After completion of your 12th standard, you can get direct admission in second year of three years Diploma course through Lateral Entry admission process. If you are interested to do Polytechnic course, I suggest you to opt for Polytechnic course after completion of your 10th standard instead of pursuing after completion of 12th standard.
