Examiners report

The best answers had clear comparative statements or were in a comparison table. The worst answers were continuous prose descriptions of the processes, as these all too often failed to be able to be pieced together to make full marking points.

About half of the candidates did not mention cell divisions, but simply mentioned "two cycles" which was too vague and instead of writing haploid/diploid, many said 23/46, which only applies to human or certain organisms.
