This has been mentioned in comments on a previous post before but I didn’t know the answer.
The 3.5 Beta exams are still available and apparently can be taken for free – The blog can be found here:
Matt W’s Windows Workflow Place : .NET 3.5 Beta Exams
Note to team, these exams are based on WPF, WCF and WF – Wasn’t this .Net 3.0?? Should these exams be marked as .Net 3.0 Exams and not 3.5?
