The requirements for the Exam Builder are the same as the requirements for Scientific Notebook. You need an IBM-compatible PC (486 or higher) with 8 MB of RAM, a CD-ROM drive, and, depending on the type of hard drive you have, approximately 50 MB of available disk space. Your system must be running Windows 95 or Windows NT 4.0. To take full advantage of the Exam Builder, you also need a local network or an account with an Internet service provider and an e-mail program.
