This product is unique in the fact that we are distributing two versions of this software title on the one CD being purchased. Version 1.1 is in full color and is suggested for use with younger students. This program has been widely distributed since 1995. In 2000, we released Version 2.0 which is in black and white. This is a more "serious" version with more depth and more instruction. The suggested use of this second program is for older students who are preparing for more advanced coursework.
