Tutoring makes sense if the grades suddenly deteriorate or if children have already written bad grades in class work several times. It is important not to wait too long with the tutoring. If you consider that it usually takes just as long to work through learning deficits as the period in which they arise, you should start with the tutoring in good time. Because if the grades are already bad, experience has shown that the learning gaps are so large that it takes some time until the student is back to the same level of knowledge as his classmates. The aim of the learning aid with the student aid is, in addition to the long-term improvement of grades, also the instruction for independent learning. Reasons for bad grades are as varied as the students themselves. Often, a change of school or teacher, puberty, moving house, a longer illness or changes in the family situation are the reasons that suddenly the motivation to learn decreases. Tutoring can be helpful even for good students, for example if they want to consolidate their grades over the long term or work specifically towards a good final exam.
