Cheaters!
I do not believe in cheaters, therefore, i give each student a different exam. Example student 1 gets exam A, student 2 gets exam B, student 3 gets Exam C, student 4 gets exam A and so on. This has eliminated the potential of those who possess the wandering eye! :-)
That is an awesome idea! i wish i could do that but unfortunately we have to jump though many hoops to change any little thing in our program.
