The last class

All classes at current year ended today. The last class was a class of Josh. I did a big mistake by the last presentation. The part of the expression did not go well because I had enthused to make presentation from Power Point. I felt nervous very much at the presentation. I was not able to read the scenario made because of the tension. Therefore, my presentation was a failure. I regret it very much. This time, I make efforts to Power Point too much and have failed. I might be worried now. It is whether the unit of the class of Josh can be taken. I feel that the unit might be lost due to this failure. Please give the unit of this class to me. It is sad that everyone parts me. Thank you for one year.
