This question piggybacks the previous GPA posting. If an applicant attended a junior college and a four year university, would the employer mainly look at the university grades? Or do both JC and university carry equal weight?
If it was me, I look at all the post high school grades. I also place an emphasis on the STEM classes. Your grade in basket weaving may be interesting but not really relevant.
I do, however, place more of an emphasis on your upper division STEM classes.
