1.7 means there are optomists among us. I'm not one of these. I'm a 23 year veteren of math instruction and feel amused that I can still be taken by a con. Frequent log-ons, nonexistant answer keys, poor service for help to use this product. Wow, what a rip-off. Great promises and a lousy product. All those "at home" educators who feel some entity is there to help - only to find it's a rank con. $35 dollars and I'm still relagated to the "Free Pages." And so it goes. Don't waste your time with this turkey. Be sure to investigate all purchases so you won't be taken in by substandard, don't care about customers businesses.
