(5 credits divided into 3 credits for the Classical Hygiene part and 2 Credits in the Health Services Organization) and Statistics (2 credits) will be calculated by weighted average between the Hygiene and Public Health Survey. The approximation will be mathematics (Example: 26.57 becomes 27, 26.43 becomes 26). For 30L hygiene is 31, 33 by medical statistic (30.5 is about 30 and praise, 30.4 and 30)In case the result is 30 and in one of the two exams there is praise then it will be 30 and praise.
