Scopus' CiteScore is closer to the "naïve" impact factor calculations; Scimago's SJR is weighted by the "prestige" of the source the article was cited at. The comparison between different metrics could be found e.g. here.
Third Quartile (51%-75%): These students have GPAs that are in the third quarter of their class. 4. Fourth Quartile (bottom 25%): Students in this quartile have the lowest GPAs and are in the bottom quarter of their class.
