First quiz was the Calculus one. To my relief, I do not have to worry too much about it since my answer got the same as the Lee’s answer. But, the physics one brought a lot of anxiety on me. I had produced a very wrong answer since I forgot to square the radius between one of the two charges at the first step… and that I considered my mark is going to be lower that 7 out of 10 marks I estimated. But one thing made me very thrilled at the present was that I was able to understand one of my classmates regarding on a Calculus topic. Lastly, I make it!!! And that had overcome my anxiety on the current Physics quiz...
