Point A you present quite well. Here we present the definition of electric circuit and the concept of current flow. In very simple terms, a circuit is a closed path with one or more paths for the flow of electricity. Current always returns from the positive end to the negative end and completes the current flow in the circuit. The importance of circuit in electrical engineering is clear.(1.4)

Most of you did well on point B. But I disagree with one of your conclusions. xyz refers to the results you have declared for the series circuit. But the circuit has two resistances which are x,y. So the total resistance of your series circuit will be x+y. If R1=x and R2=y then Rt= x+y. The difference in the circuit you mentioned is nicely presented. (3.2)

You have presented point C quite clearly. You have followed a series of instructions for the cable joint. Also you have presented the cable joint steps clearly. You didn't mention the scraping step. When you cut the insulation of the cable.(2.7)

Summarize what you learned at the end of the lesson. Here are your learning topics presented with pleasure. We are glad to have your sense of learning. (1.5)
