N2  - Precalculus is an individual course. That is, it takes your abilities and knowledge into consideration, it clearly defines what is expected of you, to provide for effective contact between you and your instructor, to provides you with the frequent opportunity to assess your own achievement and to take action based on that assessment, and it removes many of the constraints of large-group instruction, freeing you to progress at your own best rate
