I have heard some wonderful things about RAZ-kids. I am considering purchasing it for my classroom but had a few questions before I buy... 1. How many students does it allow you to enter per class? 2. Can you change the names or add names as the year goes on? For example, if I get a new student, can I add him/her into the system? Also, if I buy the program mid school year, can I enter my new class list come this August? Or will my current class list stay in the system for the entire year that I'm subscribed to the program? If that's the case, then I may have to wait and buy the program next school year. 3. How do you like RAZ-Kids? Is it also useful for accelerated readers? What are the comprehension questions like? Thanks for answering my questions!
