Yes, lateral entry is possible, and it is a great advantage for students who want to save time and start their technical career early. Many institutions offering a Polytechnic in CSE College in India allow students who have completed Class 12 with Science (especially PCM or PCMB) or those who hold a relevant ITI or technical certification to enter directly into the second year of the diploma.
This pathway is designed for students who already have some background in technical subjects. Since you may have already studied basic concepts related to computers, electronics, or mathematics, the college considers you prepared for the second-year curriculum. Lateral entry helps you skip the first year, which usually covers fundamental subjects.
This option not only saves one year of time but also helps you gain industry-ready skills faster. Many students prefer this route because they can complete their diploma earlier and move ahead to job opportunities or further studies like B.Tech in CSE. So, if you have completed 12th Science or an ITI certification, you can confidently apply for lateral entry and continue your studies without repeating the basics.
