Then, the next request was coming from his dear friend, Daniella Greengrass, who had been the head of the summer study department. This department dealt as a summer school with students, who were failing the classes and students were required to attend this department, so that they could pass the classes and didn’t have to repeat the year. But only in two classes, they were allowed to attend summer school, in order to not repeat the year. If there were three or more classes, then the student was required to repeat the year and do the same class material all over again. But the department didn’t just deal with students, who were falling behind, they were also dealing with students, who wanted to further their education with OWLs and NEWTs in certain subjects that were not offered at Hogwarts or OWL and NEWT students, who wanted to have better grades on their OWLs, in order to continue with their NEWTs.
