Candidates cannot reliably identify which items are easy and which are difficult with regard to the NCLEX scale. At the end of an examination, a candidate is usually receiving items that they have approximately a 50% chance of answering correctly. The candidate's sense of what is easy and what is difficult is relative to their ability. Because the examination is adaptive, both high and low ability candidates will think the items at the end of the exam are challenging.
