Feasibility of actually learning new math via ALEKS?

[dcan]

How feasible is it to actually learn the more advanced math available at ALEKS using their system? I need pre-calculus for my TESC BSBA/CIS plan, but it's been 20 years since high school trig and algebra 2. I tried "reviewing" college algebra from a book, then realized it is NOT the same as high school algebra and crashed and burned. banghead

I really do want to "teach myself" the following through ALEKS:

• College Algebra
  
• Geometry
  
• Trigonometry
  
• Statistics
  

I may take pre-calc through TESC, but will work through ALEKS either way on it as well. I may (read: really love to, but maybe not if I'm facing a hard C and risk screwing my GPA) take discrete math as part of my plan. I'd really like that, but that would require knowing all of the above already (well, not stats, but through pre-calc anyway). I've been a programmer for 15 years so I already do discrete math conceptually, but not as a true math discipline.

I can learn all of the above in a college course, I fully believe that. How feasible is it to learn it through ALEKS instead?

Thanks in advance for all the help. This place is fantastic.
