Uncertain of the availability of some exams.

Hi,

I cannot find some of the exams for the MCSE 2003 track.
Some of them are:Exam 70–290;Exam 70–291;Exam 70-297;Exam
70-298;Exam 70-297;Exam 70-298.

Also I wish to kwow some sites from which I can get free
online books for those courses since most of the books for
these courses from Microsoft are yet to be released for
purchase. One of the unavailable books is:

MCSE Self-Paced Training Kit: Microsoft Windows Server
2003 Core Requirements, Exams 70-290, 70-291, 70-293, 70-
294 .

Thanks in anticipation of your kind response.

Warm Regards
Myke.
