I am in 11th now. Do these 11th marks count when we apply for college? I want to go for Computer Engineering.

Sriram, hardwork done in 11th would count. So surely, if you've done the hard work your marks would be reasonable. so in an indirect way you can say it counts. Wish you the best for your career. Remember, your Career is a resultant of your knowledge combined with your passion and expression ability.

No 11th class score not count you 10th or 12th class score count when you get admission
