The paragraphs chosen in LAW2 are indeed educational by themselves. One particular strength of the EPGY courses, whether they were Math or English, is apparently the breadth of materials presented. It would be a lot of work trying to assemble on our own, contents that are as rich from other sources.

As a science person myself, I wouldn't pay much attention on the subtleties between "Done" and "Finished". :-) Most likely the EPGY programs are written by CS persons, who may also name the buttons, such as choosing "Done". But yes, why is it necessary to click the sequence of "OK-Done-Done", instead of just one click?

Question for Melissa ----- Are the "reinforcement" mode in Math and the "review" mode in English, adjustable in multiple steps or only in terms of On/ Off? Thanks.
