Can candidates find information on the historical trends of question repetition in the HP PGT exam through official reports?

Is it possible for candidates to access information about the historical trends of question repetition in the Himachal Pradesh Post Graduate Teacher (HP PGT) exam through official reports? I am interested in understanding whether there are official resources or reports that provide insights into the patterns of question repetition in previous HP PGT exams. Additionally, could you elaborate on the potential benefits of examining such historical trends, and how this information might assist candidates in refining their preparation strategies for the HP PGT examination?
