Zeker de moeite als je een groot vak op het nippertje niet helemaal rond zou krijgen.
Juiste plek voor een goeie voorbereiding op je komende toets.
Knoowy is handig voor tijdens de examens en biedt hulp bij tijdsnood. Heel gemakkelijk!
Zeer goed in gebruik en betrouwbaar. Zelf zou ik er ook samenvattingen op plaatsen.
Soms koop ik meerdere samenvattingen over 1 boek. Dit helpt mij als ik onvoldoende tijd heb om het hele boek te lezen en zelf geen samenvatting kan maken.
Uitgebreid aanbod en zeer gebruiksvriendelijk! Al meerdere malen gebruik gemaakt en zoals steeds tevreden.
Betrouwbaar platform om kwaliteitsvolle samenvattingen te vinden en een aangename en gemakkelijke website om te gebruiken
De samenvattingen zijn goed om te gebruiken als je te laat bent met leren of slecht bent in samenvatten.
