+Прошу сделать выгрузку по следующим вопросам:
+1.     Сколько человек приняло участие в тестировании (всего).
+<code>
+-- участвовали в тестировании (имеют попытку сдачи) --> 345
+SELECT count(DISTINCT mdl_user.id)
+FROM mdl_quiz_attempts
+LEFT JOIN mdl_user
+on mdl_quiz_attempts.userid=mdl_user.id
+WHERE username LIKE "dsk05-%";
+</code>
+
+2.     Результат по каждой группе тестов, на каждого специалиста
+3.     Время прохождения тестов по каждому специалисту (на каждую группу в отдельности и общее время на весь этап тестирования).
+4.     Список лиц, которые вообще не начали похождение тестов.
