It depends on what school you are applying to whether you should be concerned about general ed. Some schools
look at total GPA but then mainly focus on science GPA, others look only at specific prereq classes and science as well other factors such as recommendations, volunteering, past experience, entrance exam scores, etc. I have been looking into 3 different schools and science GPA and entrance exams are the most important. Overall GPA is somewhat important for 1 school. So I am focusing on making all A's in science and working toward getting an awesome test score for the TEAVs exam.
So, you should really research (where you intend to apply for nursing school
) what they are looking for in applicants and it could be that overall GPA is important or it may not be...
As an example, one of the schools I am interested in only uses certain classes to factor total GPA like Dev Psych, math, all sciences, sociology, and a few other specific classes required - but all my other classes don't factor into the GPA - I hope that makes sense. However, a different school I am interested in looks at the total GPA but mainly focuses on sciences and entrance exam scores.
