The best control group would be another section where students all had to spread their deadlines out equally. This would help to eliminate the possibility that the students who spread out their deadlines had better grades for reasons unrelated to their deadline choices, such as being better students overall. This control group would eliminate this potentially confounding variable and allow for a more accurate interpretation of the results.
