Резултат от изпита по C# – част 2

Изпита на 22.01.2014 (сутрин) приключи със среден резултат, само 279 точки, но изводите са вече направени – необходимо е повече старание и време за по-добър резултат.

Задачите бяха много интересни, а за следващия курс по C# част 2 ще се постарая да съм решил всички давани задачи до момента, плюс тези от Алго академията.
