SOP/LOR

SOP/LOR

I want to pursue an MS in CS degree from US fall 2019, with preferable data science track. My GRE score is 318 (162 Q, 156 V) and TOEFL score is 104. I have work experience of 13 months so far. I have a GPA of 3.4 on a scale of 4, and no backlogs. However my marks in the relevant theory subjects during my B.E. (e.g. data mining) are slightly low, but practical marks are very high. Should I bring it up in my SOP, and should it be mentioned in some way in the LORs?
