All the 27 types can be classified into three groups, ranging from easy (K) to difficult (A). However,
it may be admitted that certain types of questions are more difficult to construct than others because
some forms of questions are more amenable to testing of a particular objective in relation to a given
content element. Similarly, it is more difficult, sometimes impossible to develop, higher-level objective
(A) using lower-level content element (F). Still, in other cases some forms cannot be used to test
particular content element efficiently. Thus out of 9 sets of questions, as we proceed from 1st to
ninth set it requires more expertise to develop than others. Questions in 9th set are the most difficult
to develop and those of 1st set are the most easy to construct. The first question is based on fact
testing knowledge objective using objective form, whereas the last question in set 9 is based on content
element principle and of essay-type testing application objective. If one tries to frame question on each
of the 27 questions, it would be possible to judge which of them are quite difficult to handle.
