Difference between 70-294 and 70-297?

What is the difference between 70-294 (Planning, Implementing, and Maintaining a Windows Server 2003 Active Directory Infrastructure) and 70-297 (Designing a Windows Server 2003 Active Directory and Network Infrastructure)?
Comments
- 297 is the halo exam for the MCSE 2003 so the case studies can include everything from 270 and 290-294.
- 294 focuses only on Active Directory (with a special emphasis on group policy).
- 297 is comprised of multiple case studies followed by questions related to the case study rather than individual questions througout. The format alone makes this one a challenge and several people - including myself - have failed because of it.
- The available study material is almost useless.
