Recently, Professor McGonagall has noticed increased rates of cheaters in the Slytherin house. Can you help her find what mark the cheaters got so she can give them all a 0?

The only hint she provided you with is that:

All the cheaters got the most common mark on the test.

Note: there will only be 1 most common mark.
