WIRIS collection is intended to speed up your work in class. It is a free repository of real classroom exercises done and shared by teachers. Its aim is to cover all the topics in mathematics at any level, and it already contains a good number of exercises.
WIRIS quizzes is multilingual and it is today available in the following languages:
What happens if the student introduces a correct answer that we were not expecting? In other words, what happens if he gives an expression that is mathematically equivalent to the expected one, but that looks completely different to it?
The random functionality in WIRIS quizzes allows creating random questions that minimise the possiblity of cheating in an exam. Every student will get a different set of questions, so his answers will be of little use to his neighbour.
