While law schools set their own criteria for admission, there is currently a national trend toward taking a holistic approach to admissions. Generally, if you received a B or higher, then I would consider taking the grade. If you are receiving a C or lower, then I would consider taking the CR/NC path and adding an addendum. Law schools will mainly care about it not becoming a trend in the grand scheme of your transcript and will be understanding. Students are encouraged to contact a pre-law advisor at the University Career Center for guidance on particular circumstances.
