        Core C++ for Qt Developers Exam Curriculum 022-001
        This document defines the curriculum for Core C++ for Qt Developers exam. Digia
        provides three kinds of Qt certification exams:

        • Qt Essentials
        • Widget UI with Qt
        • Core C++ for Qt Developers
          If a candidate passes Qt Essentials exam, he or she will receive Digia Certified Qt
          Developer status and the corresponding certificate. If he or she additionally passes either
          or both of advanced exams (Widget UI with Qt or Core C++ for Qt Developers), the
          candidate will receive Digia Certified Qt Specialist status and the corresponding certificate.
          If a candidate has already taken two exams and passes the third one, he or she will
          receive another specialist certificate, where all three passed exams are listed. It is also
          possible to take an advanced exam before the essentials one, but the candidate does not
          receive any certificate in this case, until the essentials exam has been passed.
          The exams are organized by authorized PearsonVUE test centers. Look at the details of
          test center locations in http://www.pearsonvue.com/digiaqt/. To see the nearest test
          center of your location, use Exam Scheduling links at the bottom of the page.
          Digia prints the certificates bi-weekly using a print house in Germany. After printing, the
          certificates are sent by mail to the exam candidates.
          Core C++ for Qt Developers exam will test your C++ knowledge, required to write highquality
          Qt programs. The exam includes a set of multi-choice questions and the candidate
          must select the correct statement(s).

                      I have created two wiki pages for the two exams.
                      "Widgets UI":http://qt-project.org/wiki/Curriculum-block-for-Qt-Widgets-UI-advanced-certification
                      "CoreC++":http://qt-project.org/wiki/Curriculum-of-Qt-advanced-certification
                      Hope the indentation helps.
