After reviewing the uCertify PrepKit for the exam 70-448, Jason said, “The UI has got separate sections for tests, study materials and progress tracking. The tests can be taken in two modes – learn mode (where you can review your answers immediately and read the notes also for it) and test mode (where you would be able to see your answers and score only at the end of the test). uCertify has neatly classified the tests so that there is a diagnostic test in the beginning to assess your level, practice tests to improve your skill levels and the final test (which I think is a bit harder than the real one).”
