I don’t know if this has been mentioned yet, but I do not suggest taking Computer Science A or AB in hopes of exempting CS 100. While Alabama WILL allow you to exempt CS 100 with a 4 on the Computer Science AP exam, Computer Science A teaches Java while CS 100 teaches C++. So, if you did exempt CS 100 with AP credit, you would be most likely be behind or very confused in the following CS class.
