Do TTh sections also have three jokers?
Yes, this needs to be clarified: to be fair, both MWF and TTh sections have 1 week worth of their lowest HW scores as “jokers”. So, three hours for MWF correponds most weeks to 2 HW for TuThu. We take the same percentage off from the bottom scores from everybody and this percentage is measured by 3 hours for MWF.
