Did anyone else get this one wrong because they thought E was too good/easy to be true? I felt that E was more sufficient than necessary because it was so strong...

This is kind of a random question so late in the curriculum, but I have been wondering how one should map out these questions while taking the LSAT online. I know we are allowed scratch paper, but is it worth taking the extra time to physically map out these questions like J.Y.? It would be so much easier to do it directly on the exam... are there highlighting and underlining options? It is my first time taking it online. #help
