Things are challenge

To learn the computer science, the logic thinking is the most important thing we should care about. Once you have a clear logic, you could understand the codes much easier. I believe my logic thinking is not bad. I can understand most of the code very fast, but there are still some thing really confuse me. The first thing is the code "map-image" I could not understand how they use this code to achieve "number-->image" and another one I know how to use but could not understand well is "list-color". I am confusing how they connect the number to the color that well.

Two Projects

I will be  really happy if the professor could give us the solutions of the two projects before the final exam. I still did't get some of the question of the two project. I know how to do most of them, but can not make the program run perfectly. I hope we can get the solutions so that I could understand why I was wrong.

History and Code

For the whole course I think the history of computer is really hard.  The reading material are kind of messy.  For the two term tests, even though I read all of the material,  There were still a lot of questions I didn't know how to answer. I hope we can get a clear structure about what we learned, that will help me prepare the final exam  well
       
 The code that we learned is not that hard, but the textbook could not give a clear explain of all of them. And some of code have a circle structure. I do know how to solve them, but I think there must have a way to solve them faster then that.
