What examiners said
Most candidates knew that the male gamete is much smaller than the female gamete. They also knew that very few female gametes are released each month. Candidates were less precise in their understanding of how the male gamete moves. Many simply stated that it can move by itself. This mark was awarded to candidates who stated that it has a tail or that it swims.
