Ball Point Sketch

The class at the beginning of the test which took 40 minutes. However, they could leave after 20 minutes into the test. After that, they would have to stay till the end of the test.

The second sketch showed only a few students left 20 minutes into the test, they had to stay for another 20 minutes in the room.

I used normal ballpoint pen for the sketches since the fountain pen was dry.
