1. iStudy has been designed to work best in a school or group environment with students developing their own lessons and trading them with their peers. VBA with Excel works very well with both Mac and Windows individually. VBA and Excel work very well between the two platforms. Anything created on a Mac can be viewed on a Windows machine and vice versa.
2. At the moment the development of the software has been much faster due to iStudys marriage with Excel. We do however have plans to integrate Excel’s spreadsheet functions directly into iStudy.
3. The bottom line is that iStudy works well with Excel 98 through Excel XP and with Windows 97 through Windows XP while at the same time iStudy works flawlessly in Mac OS X with Excel X. iStudy lessons are easily exported and imported between the two platforms.

Thank you for your interest.
