Traduction - Allemand-Turc - Schule

in german form of this text it s written as "Schülers/in" to point the masculine and feminine forms of the plural word of student ;however, in turkish there is not distinction between words as masculine or feminine so i corrected it as "Öğrencilerin". And i corrected the "zamandan" with "tarihinden" because the gap is to be filled with a date which indicates the negative behaviours of the student started .
