Hello Aspirant,

This really cannot be compared as both colleges are good at their specific branches and if you want to do ECE then PSG College Of Technology is good to go and if you want to opt for CS branch then Coimbatore Institute Of Technology is good and as you have mentioned you are weak in Physics and good in CS and Maths I would suggest you to select CS branch into Coimbatore Institute Of Technology.

Hope this helps

Good Luck
