To make the course material more interesting and effective, you will be led through an imaginary scenario where you will have particular goals to meet. So the material will make more sense if you go through it from beginning to end, rather than by skipping around. If you really do want to skip around, though, then I'm not going to stop you. :-) Just click on a link in the table of contents on the left to jump to that topic.
