GEO 793 or CGEO 793

Initially enrolled in GEO 793 with Hummonds, but saw CGEO 793 with Manshouri, and that's on Monday. The in-person GEO 793 is split into 2 sections, and i seriously don't want to commute. I only have classes on Fridays, and I don't want to commute that much. Saw that the reviews for Hummonds and Manshouri are both okay, but which one should I take? Wouldn't have to commute if I take the Chang version, but is it now in person for exams for CGEO 793, or is there a lockdown browser bc I know some rules changed over the years.
