Old tests in Python from Fall 2010 onward
Starting in Spring 2018, CompSci 101 was taught using Python3, which means all prior exams will be in Python2 and therefore the answers are based on Python2, not Python3.
In Fall 2012, CompSci 6 was renumbered to CompSci 101. Since 1994 CompSci 6 was taught in C++, then Java and then Python starting in Fall 2010. Hence, this is from 2010 onward.
