Nadat ik Knoowy ontdekt heb, ga ik regelmatig op zoek naar eventuele bruikbare samenvattingen! Heel erg handig!
Super handig, echt een goeie site. Ik ga dit in de toekomst vaker gebruiken!
Kijk voor samenvattingen ook eens op Knoowy. Goede samenvattingen en betaalbaar.
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.
Downloaden maar! Goede site met goede documenten. De prijs wordt aangepast o.b.v. de beoordelingen.
Bespaart héél veel opzoekwerk en stress ook zeer overzichtelijk en gebruiksvriendelijk.
Zeker de moeite als je een groot vak op het nippertje niet helemaal rond zou krijgen.
Tijdens mijn studie aan de Arteveldehogeschool en KU Leuven heb ik opdrachten gemaakt die ik nu via Knoowy deel met andere studenten.
