There are two options for purchasing Escalation. You can purchase a Class Set or the School Version. The only difference between the two packages is the number of CDs included. The Class Set includes 15 CDs while the School Version includes only 2.
You can use the simulation on as many computers as you want at the same time no matter which version you choose, but the simulation runs very slowly without a CD. Once you purchase the simulation and receive your user name and password, you can log in and play the simulation with or without a CD. The class set is ideal for allowing a whole class (2 students each at 15 computers) to play the simulation at the same time.
See the comparison chart to help you choose which option is best for you.
