see if you want to take admission on polytechnic then you have to pass atleast your 10th class from any government recognise school.
you should have atleast 33% in your boards then you can take admission in polytechnic in mechanical, electrical, mining, CST or any branch of your choice.
The collage has very Big campus as I visited any other polytechnic the campus has good infrastructure as all lab are present in the campus the classes in the Campus are not to good such as same old school benches black board and all.
