<p>I have no idea what the "R" is. Does it stand for Monday something?</p>
<p>R stands for Thursday (T is Tuesday). So that course is held on Mondays and Thursdays.</p>
<p>Thanks so much. I had no idea what that meant! </p>
<p>Why do they put only an “R”? I feel so stupid for asking this1</p>
<p>It goes back to ancient Chinese times. Right after Lun Tsai invented paper, he created the abbreviation for Thursday…</p>
<p>Chances are their first computerized registration system was written in ancient times and it was easier to give every day a one-character abbreviation. Luckily my college hired a more skilled programmer. Our Thursday is Th :)</p>
