Prerequisites for admission
Students must have fulfilled all the prerequisite requirements indicated in the study plan: Biochemistry and Fundamentals of Human Biochemistry, Techniques in molecular and cellular biology, General Pathology and Immunology.
Assessment methods and Criteria
The exam consists of two written tests, both mandatory and performed on the same day.
The first written test, lasting 1 hour, consists of 60 questions (30 for clinical biochemistry and clinical molecular biology, and 15 for clinical pathology and 15 for diagnostic imaging ) which include:
1) multiple choice questions (70-80%);
2) short answer questions (30-20%);
Each question/exercise achieves 0.5 point.
The test is passed if the score total is equal to or greater than 18.
The second written test for the medical statistics part, lasting 1 hour, consists of 30 questions (20 for statistics and evaluation of the evidence in medicine and 10 for diagnostic imaging, which include:
1) open-answer questions with the analysis of statistical problems (50-60%);
2) multiple choice questions with brief explanation of the choice (40-50%);
Each question/exercise achieves 1 point. The test is passed if the score total is equal to or greater than 18.
Both tests aim to ensure that the student has theoretical knowledge on the main biochemistry and clinical diagnostics methodologies and knowledge of the principles underlying advanced diagnostic techniques, as well as the necessary basic statistical skills for observation and measurements in the presence of experimental uncertainty and the evaluation of scientific evidence from data analysis in biomedical research. The following evaluation parameters will be considered: correctness and completeness of the answers, and ,concerning open answers, the ability to organize the responce providing basic knowledge, critical reasoning skills and competence.
The final mark, will be expressed in thirtieths, resulting from the average of the score obtained in the first and second written tests rounded to the next larger integer.
The test results will be communicated via e-mail, through a verbal service.
