Depending on the field you are thinking of for your master's degree, there are probably many schools that won't care about how well you did on your Sophia courses. Most graduate programs that I am aware of, admissions is handled by the department, not the school admissions. Though most schools will require that you pass through the school's admissions/registrar's office, this is generally a formality where someone reviews your transcript to make sure it meets the general undergraduate requirements.

The department reviewing your application for graduate studies will, in most cases, be a lot more interested in you as a person than they will in what specific grades you got for ACE credits on your transcript. If you applied to a highly competitive program at a competitive school, these things might come into play, but outside of that, most graduate faculty are looking for dedicated students that will represent the school well as graduates, and people who are committed to learning and to the field.

Perhaps you are focusing on a particular field or school where this is an important criteria, but if not, earning 97% on everything is not something I would worry about. And if it is... it should absolutely be achievable with Sophia if you put the effort in.
