Some courses are currently available as online courses.
Students are able to take these courses at any location in the world, provided that they have access to the Internet via a good computer. The online courses are not the same as correspondence courses. Learning takes place in a virtual classroom according to a semester schedule and in communication with both other students enrolled in the course and the professor. Students answer questions presented in the course material and carry out assignments which they submit electronically to the professor. They also participate in threaded discussions with fellow-students and take examinations at scheduled times on their computers.
