You should score 80 percentage or more for better chances of admission

Hello dear, it may create some problem as some of the corporates want a percentage of 60 throughout the academic past unofficially. Since other two percentagesare above 70 so it will give u relief. You need to perform steadily in personal interview. Hope u do well and get a good job. All the best. Thank you.
