Hello Diksha
You wanna know whether with getting a compartment in one of the subjects in 12th standard will effect your chances for getting into law colleges. You need to have more than 45% in your 12th standard of you are a general category student and 40% for SC /ST. .since you have a compartment in one of the subjects so you have to first clear that subject get passed in it and than you will be eligible for getting admissions in colleges.
Best of luck
