Samenvattingen

Hallo! Ik ben een student biomedische laboratoriumtechnologie aan HoGent. Ik verkoop mijn samenvattingen dus hier twee puntjes over mijn samenvattingen: Ik vat vaak heel gedetailleerd samen omdat ik liever uit 1 volledig document studeer en ik gebruik vaak afkortingen of probeer alles in stapjes te zetten. Als je een afkorting /zin/woord.. niet begrijpt mag je mij zeker een berichtje sturen! Veel succes met de komende examens! Groetjes x
