When you select a tutorial in one of the 20 subject areas, ChemTutor® Excalibur displays a question that you will need to be able to answer once you have mastered that subject area of chemistry. If you already understand how to solve that type of problem, you can go ahead and answer it. However, if you have no idea how to answer that question, you can click on the LEARN button.
