Since the painted work is generally done in a quick-drying medium and should be completely dry before it is sent, better paint quality is suggested. When acrylic paint is given for examination work, it should be diluted in water. All colours used should be of adequate quality. In case pigment coloured pencils or chalk are utilised, they must have a reach and quality similar to that of paints and should be recognised and dried at the examination hall before the work is given off to the invigilator.
