- Jeg har lavet en note-samling til vores biologi eksamen. - Rødt er det som jeg synes der mangler oplysninger om, fra vores pensumliste. Men I må meget gerne lige tjekke de hele igennem og tilføje jeres guldkorn. - Men jeg forventer, at I tilføjer jeres egne noter. Dem må I meget gerne markere med grøn og sende dem til mig, så laver jeg til sidst en samlet og sender rundt ;)
