Ik verkoop samenvattingen om andere studenten te helpen en tegelijk wat bij te verdienen.
Knoowy is zeker aan te raden. Goedkoop en je krijgt meteen je document!
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.
Een echte aanrader! Je vindt er heel wat nuttige samenvattingen!
Prima samenvattingen van veel verschillende vakken die je goed kunt gebruiken.
Knoowy is heel handig om te gebruiken. Zeker aan te raden.
De samenvattingen zijn goed om te gebruiken als je te laat bent met leren of slecht bent in samenvatten.
Ik ben altijd erg blij met de samenvattingen van Knoowy.
