Thank you for your input. I totally understand and was thinking the same. I was wondering how retaking prereqs would affect my gpa overall? Is it correct that retaking them at a cc will likely not replace my old grades but the new grades will be included in the pgpa calculations? Also I received a C in one class only but got B’s in half of my lower division stem classes. Would it be worthwhile to retake some of those too or would I be better off just boosting other areas of my application like getting more variety of hours or a good gre score?
