The final exam of the Physics 1 course consists of a written test and an oral colloquium. In order to pass the written test a student must get a mark larger or equal to 18/30. Te final mark is determined as 1/3 of the mark of the written exam + 2/3 of the mark of the oral exam, with some corrections depending on the level of the oral exam. Target of the written test: minimum 18/30 Target of the oral test: minimum 18/30
