When we say randomized, we mean it. In addition to reshuffling people usually have in mind, in our system, individual questions can be randomized so that each student has to solve the same question with different numbers. You upload one example question, we take care of the rest for you.
Better yet, the more you use our system, the more accurate the difficulty level of each question would be. This means after a while, you can create an exam by specifying your target difficulty level. The result? A fair and unique exam for each student.
