    Objects, timing and methods of assessment

    The written exam consists of five questions of 4 points, ie a total of 20 points. About 50% theoretical questions, other half calculations.
    In the calculation exercises, an answer gives four points if the calculations are complete with the right values ​​and the correct answer. Careless errors give deductions.
    The lab is assessed with points 1-5 per lab, ie a total of 10 points. The report is primarily assessed, but the own activity during the laboratory session is also taken into account.
