Hello Shivam,

Generally some big Multi National Companies (MNCs) use to setup the parameter of 6:6:6 which means in 10th, 12th and graduation you need to score 60% or more marks to be eligible for interview. Above parameter may differ according to company needs.

If you want to go in Computer Science background than major companies demand the percentage of 12th.

I hope this answer helps you.

Good Luck!!
