For AP CSP, the class is basically up to you. Mr. Crow will teach you a topic, then have you apply it with a set of lessons on Code. org. You can move as slow or fast as you want, If you ever need help he is ALWAYS there to help, which is why he is my favorite teacher throughout high school. The PLTW Intro to programming class is pretty much the same. For AP CSA, be prepared for it to be a lot harder than the other two courses. He will probably have you open a couple of JAVA files with all your notes and examples on it, which I HIGHLY recommend. Those notes really helped me succeed.
