Some features of informatics tasks given at the Bulgarian National Competitions for the ``pre-master'' school students group (9-10th grades in 12 grade school, i.e., 16-17 year old students) are discussed. The study covers the period 2004-2011. The considered group of students is important, because among them will appear candidates for the national team in the next one or two years. While tasks for the ``master'' group are complicated and not easily made into a system, the tasks examined here are more suitable to be analyzed. In the paper, an attempt is made to arrange these tasks using keywords, and to introduce a coefficient for measuring relative difficulty. The work continues two previously published papers of the same authors in this journal, devoted to the tasks for the intermediate and youngest students.
