In practice CLAD exams 1 & 2, descriptions of correct answers are directly related to the question asked. Starting with Practice Exam 3, the user is directed to a subject reference link.. Given that the question has four possible answers, more than one of which may be plausible, the answer descriptions presented in the first two exams not only gives the correct answer, but also the reasoning as to why it is the correct answer. Much, much more helpful to the student. I know providing a link is likely easier for NI, but it is also like a Google search with 2,000,000 hits.
