Inheritance & Polymorphism

Over the weekend, we were supposed to do 28 multiple choices from the Barrons Book. Inheritance was very simple for me, its come to me like second nature because it was basically a review but I got stuck on Polymorphism. Unfortunately I got only 19 questions of these right and this time I did every single multiple choice question by myself. I did not get nay help on understanding and I did not want to slack of because I really believe that I need to apply myself more properly in this class, so I will be more focused in class this week and I will be on top of my coding. Apart from that, I did try to understand and solve the questions that I got wrong but Polymorphism is a concept which will take some time for me to understand like recursion did at the starting. Over the weekend, I also took the advise from Mr.Daly and I did like 15 JavaBat questions all from different sections like  I did some from Logic 2 and I did a few Recursion problems and some String-2 as well. Just so that I get better at the coding because I feel that my weakness is defiantly in the free response but I need to build up on it rather than slack it till later. I usually do well on multiple choice right. Also I tried  to go over the Sudoku coding that we did a while back, and I tried to code it myself. I saw that there was a lot of problem and confusion so I will be working on that throughout next week. Apart from this, I need to work on the grid world as well, which I will hopefully get done and post it tonight.
