Hello akshara ,

You need atleast 800 marks out of 960 in keam 2022 to get under a 3-digit rank like 500. Also you have mentioned that you have secured full marks in PCM , so it will be a very good chance for you to get admission in good government colleges.

Name of some of the colleges are :

• Government engineering college thrissur
• college of engineering trivandrum
• government engineering college Barton hills trivandrum
• government engineering college sreekrishnapuram palakkad
• government engineering college idukki
• MAC kothamangalam
• TKM kollam
