A system and method for an interactive, Internet-based videoconferencing multicast operation which utilizes a video production studio with a live instructor giving lectures in real-time to multiple participating students. The videoconference multicasting permits the students to interact with the instructor and other installations during the course of the lecture. In the case of software training, the system and method also utilize Internet-based application sharing and collaboration to permit the students at remote locations to drive a studio-based computer with the software for which the training is being given. The software screen is then used as a background with the instructor being able to literally point to areas of the screen which are being discussed. The instructor has a set of monitors in the studio which allow him/her to see the students on-location. In this fashion, the students can see at their computer screens the instructor "walking" around their computer screen pointing at various items in the screen. Furthermore, a system and method for on-line testing, evaluation and reporting is disclosed wherein test questions, which can be created on the fly by a test administrator, are stored in a database and associated with one or more test numbers and whereby each time a student requests to take a test, the test is "built" and the order of the questions is randomized to avoid cheating. Test evaluation data is cross-correlated and made instantaneously available to students and their sponsoring employer.
