The Precision Learning Track is available as an alternative to the content within the course. This means you can elect to take the entire course or to follow the Precision Learning Tract, which will present only the portions of the course pertaining to material you missed on the pretest. Mastery tests at the end of each unit verify the level of skill attainment and point you back to any topics requiring further review. The result is a closed-loop, verifiable learning system. At present there is no NETg CD client for the Macintosh.
More memory is better.
