Aleks intro to Statistics

[wandac]

I realize this is an old thread. My son is currently 30+ hours into the ALEKS Intro to Statistics initial assessment. It is all foreign to him, but with diligence he's on problem 18/25 of the initial assessment, and with no idea of how he's doing. At this point, the problems are beyond his ability to find anything similar elsewhere on the internet to help him learn how to do the problem. Would it be better to hit "skip" on the rest of the assessment problems and put his time towards assembling a "notebook" of examples, or should he continue to dig and beat his head against his desk in finishing this initial assessment? At this point, he just wants to "get through with it" in the least amount of time possible. I've already informed him that if he ever has to take a class that has statistics as a prerequisite, he must go back and take a full-fledged statistics course to learn this stuff well.
And assuming he does proceed to the pie, should he print every single example problem, even examples from the parts of the pie that were considered "mastered"?
Is it ever better to just quit the course (after making a notebook of sample problems) and re-initiate the course to get a brand new assessment, or is it better to trudge through the course and keep taking assessments when the green bar is over 72%?
Looking for the best 'get-er-done' strategy.

Also, the stats calculator in ALEKS is nice. Sometimes he has to log into ALEKS just to access the calculator. Is there a free internet-based calculator that has all those stats functions?
