For grades fifth to twelfth, a 1 to 10 grading system is used with 10 being the best, 1 being the worst and 5 being the minimum passing grade. The system of continuous assessment is also used, with individual marks for each test, oral examination, project, homework or classwork being entered in the register (these individual marks are known as "note"). There must be at least as many note for a subject as the number of weekly classes for that subject plus one. Some subjects also require a partial examination at the end of the semester ("teză"). This requirement is however regulated by the Ministry as mandatory. The partial is valued at 25% of the final mark, and for grades 5 to 8 it applies to Romanian Language and Mathematics and only in the eight year, Geography or History, and in the case of a bilingual school or one with teaching in a minority language, that particular language. At the end of each semester, an average is computed following a four-step procedure: first, all marks are added and an arithmetical average is computed from those marks. If there is a thesis, this average, with 0.01 precision, is multiplied by 3, the mark at the "teză" (rounded to the nearest integer) is added, then everything is divided by 4. This average (with or without "teză") is then rounded to the closest integer (5/4 system – thus 9.5 is 10) and forms the semester average per subject. The next step is computing the yearly average per subject. This is done by adding the two semester averages per subject and divided by 2. This is not rounded. The last step is adding all the yearly averages per subject and dividing that amount by the total number of subjects. This forms the yearly grade average ("media generală"). This is neither weighted nor rounded. If the yearly average per subject is below 5 for a maximum of two subjects, then the student must take a special exam ("corigență") at the failed subject in August, in front of a school board. If he fails this exam, he must repeat the entire year ("repetenție"). If the yearly average per subject is below 5 for three subjects or more, the student is no longer entitled to the special exam and must repeat the year.
