During our block teaching we were told to conduct a test of 20 or 25 marks. We had to choose a topic from any standard and conduct the test. The topic for my test was Light, Shadows and Reflections for Class VI A. I conducted the test for 43 students from which 5 were absent. It was a great experience for me to conduct the test. Thanks to Anna Ma'am for training us to set the Question Paper and the Blue Print.
