Those who only meet the minimum requirements are only conditionally admitted and have to pass their first two OMS CS foundational courses with a grade of B or better before being fully admitted. Nine modules are now available from Udacity, including Sebastian Thrun's Artificial Intelligence for Robotics which has been updated for the OMS CS to include a final project where you must chase a runaway robot that is trying to escape!
Via Udacity they are self paced with videos, transcripts of lessons and in-lecture quizzes, but no assignments and support is via Student Forums whereas from Georgia Tech they will be scheduled and deadline oriented, will include projects and have support from Georgia Tech TAs.
This is because, with tuition entirely online, students are charged as little as 6,600, less than one-sixth of the cost of an on-campus equivalent at 45,000. The OMS CS courses have been developed in conjunction with Udacity and AT T and are delivered using the mooc model. If you don't possess the entry qualifications but are interested in the courses that make up the curriculum there are two other choices. One is from Georgia Tech Professional Education, with a charge of 399 per course and leading to a certificate and Continuing Education Units. Preferred qualifications for admitted OMS CS students are an undergraduate degree in computer science or related field (typically mathematics, computer engineering or electrical engineering) from an accredited institution with a cumulative GPA of 3.0 or higher.
The number of students for all the courses reflects the length of time they have been available as well as the popularity of the topic. The same, or similar courses are listed on the Georgia Tech Professional Education Online Computer Science Courses page and those interested are invited to join a mailing list to be notified when they become available.
