In the 'exercise universe' the module titled 'Systems of Equations' is positioned too high. It is quite difficult, and the surrounding modules do not really contribute or relate to this exercise. Moreover, the other exercises concerning systems of equations, positioned significantly lower, are easier and should be used to build skill and confidence in preparation of the module 'Systems of Equations'.

A more general note. With the increase of modules this universe is becoming rather chaotic. I would recommend grouping some of the exercises together, to make everything more perspicuous. Such grouped models could be titled 'Basic Arithmetic 1', 'Basic Arithmetic 2', 'Linear Equations', 'Basic Trigonometry 1', etc.
