Preparation for Recertification

    My CCNA is going to expire on March 2.  I need to recertify.  

    I found out that I can take the ICND2 alone and that will
recertify me
(http://www.cisco.com/web/learning/le3/le2/le0/le9/learning_certification_type_home.html).
    Since there is some new material there, I'd like to gauge my
knowledge.  Short of paying a bunch for something like Transcender or
Pass4Sure, is there a more economical way to check my knowledge before
I blow the money on the exam?  

    I teach CCNA so I go over a lot of the material for the
students.  But I've only been teaching the new exploration courses for
a semester.  I understand there is some wireless information, new
frame relay information, and a few other things that weren't on the
previous exams and I haven't covered them in class yet.  

    Any feedback you can provide would be appreciated.  

    Regards,
