There's this class named "Data Stuctures," and a class to start programming in C or you can even jump into C++. I don't know what Data Structures is comprised of and I was wondering if this would be useful to take because I'm not very good at Java, but I found a really nice chat and they help me out. I also bought a book for my class and someone is sending me some e-books for java. So what are your opinions on which class to take or should I just take them in sequential order?
