The text is clear and easy to read and the images compliment the information. Its design is not crowded and flows well for the learner. There is no special software needed for the site. As mentioned earlier, the program has been tested on various screen resolutions to ensure a quality presentation and can function with the different platforms and browsers. All the information is broken up and defined clearly throughout the program.
Navigation is clear and as stated earlier, easy to follow through hotlinks.
The navigation within the lesson gives the option to move to the next part, without completing all of the practice exercise. It does a good job of explaining things clearly to the learner. I feel the learner can grasp the concepts taught. It provides them a needed amount of practice to accomplish the goal of the program. It can also be a great refresher site to sharpen those Math skills.
