3. 'Essay' (open end) question: these questions let the user simply write the answer. You may use them for manual evaluation of their skills, or to obtain some feedback as survey. But, you can also assign correct/incorrect answer. WatuPRO will check for match (not case sensitive) and if the answer matches one of your answers, the corresponding points will be assigned.
For example, consider the following question:
Which country in the world has highest population?
(This is an open end question, but if you type 'China' in this test exam you will receive 3 points. In other cases you will receive no points. But you can decide to assing negative number of points to some very wrong answers like 'Luxemburg' for example).
