The exam is a set of three written exercises regarding the main topics of the course.
Each exercise is made of several questions that need a numerical answer.
The sum of the points obtained by answering to the exam question leads to a maximum of 25/30 points.
The remaining 5 points are assigned on the base of the evaluation of the design work (design of a simple reinforced concrete building) done in groups during the course.
