According to the Presbyterian College Admissions page, regular campus tours do not occur on Saturdays or Sundays.
During the fall, however, Presbyterian College offers special tours for prospective students that are held on Saturdays. This year, the "Preview PC" days are happening on October 25 and November 1. These events include a class visit and occur in conjunction with college football games.
Before you go, you should register your interest with the application office online. Also, check out Noodle's articles on questions to ask on a college visit and other tips for college visits and campus tours.
