Documenting breakout

Almost at the end of the Java course, and have to document to process of making the breakout game. There's also the exam next week in Java where I need to spend a bit more time studying. Feeling pretty confident, and a lot of the exam is multiple choice options. But I do feel like I need to spend some more time with two things in particular; interpret UML's correctly and also understand some design patterns like adapter and facade. There has always been a question about some design pattern, like the previous exam has been on Singleton pattern where there can only be one instance of that class.

Also I got a 55/60 on HTML/CSS course. Proud of that one. I didn't score on one question but that was because the exam first asked about the width of an element, but than changed to the height. Was a error from the teacher, and if you had calculated either one correctly you would have scored. And I did calculate the width correctly, but I ended up entering the height for the element since that was the final prompt for the question. What I forgot to include in the height of the element was the size of the text inside. Other than that I missed one point on another question. I believe it was in a form where you should have the URL it was supposed to send to inside the form element, but I ended up putting a href attribute in a button element (which I don't think it can have). Still, highest grade on the exam. Just my ego that would have wanted the points for the element size. But it wouldn't change the grade anyway...

So I'm still trying to just quickly go threw the rust book a little every day but since there's the exam coming up and I would like to have the documentation done most of my time is spent on that.
Looking forward to starting that C# course though!
