hi,

see the marks criteria depends on the particular organization and their norms. recruitment process and eligibility criteria is liable to change from time to time. however at this score you are eligible to apply for the most of the government jobs which is intended for bachelors level. for private jobs accept for mncs the most of the private organization gives priority to skills rather then score. however if you are intended for engineering, you may not eligible for many of the mncs since 12th marks criteria is 60% or above in most of the tier 1 mncs.

hope it would help.
