Drawing bottles and glasses

Today I found these images of last summer's year 9 internal art exams . We ask students to draw a bottle and a glass using a pencil. They have one hour and 20 minutes to do it and we ask them to try to apply all the techniques they have learned to the best of their ability. We then mark them on specific criteria such as quality of line, shading, mark making, composition etc. Looking at these I am impressed with how our students can draw at this age.
