IT IS GOOD TO SEE THAT YOU ARE LOOKING FOR THE HIGHER STUDY IN TECHNOLOGY AND ALSO DECIDE TO GO FOR MASTER,S DEGREE. TO GET ADMISSION IN ENGINEERING COLLEGES THERE IS NO NEED TO HAVE 12th CERTIFICATE AS YOU HAVE COMPLETED THE POLYTECHNIC DIPLOMA. IT WILL ALSO HELP YOU TO GET LATERAL ENTRY IN ENGINEERING COLLEGE. AFTER COMPLETING THE POLYTECHNIC DIPLOMA YOUR ENGINEERING COURSE MAY BE OF 3 YEARS DURATION. ABOUT ALL THE JEE MAIN COLLEGES OFFERS THE LATERAL ENTRY SCHEME. THERE ARE MANY OTHER COLLEGES WHICH ACCEPT THE LATERAL ENTRY.
