Difficulty 1 - Theory is hard to understand Many students have problems understanding issues, especially the science courses, because of its technical complexity, a necessity of abstract thinking and the fact that those concepts are not entirely tangible Difficulty 2 - Less practice and experiment Practical exercises, mainly based on specialized research equipment, must be carried out under supervision; therefore, students cannot self-configure lab equipment, experience states of emergency or effects of misconfiguration which may lead to equipment damage.
