WEST LAFAYETTE, Ind. (AP) – Purdue University is offering a popular introductory computer science and programming course for free to high school students in Indiana.

The online course titled “Introduction to Object-Oriented Programming” offers an introduction to computer science and the Java programming language. The course will not be graded or count toward credit requirements, but it covers material similar to the computer science Advanced Placement course and could help students to test out of freshman programming classes at Purdue and other schools.

Purdue says the self-paced course is available to any high school student in Indiana, including those who are home schooled. Enrollment for the spring semester is open through Dec. 1.

Students interested in enrolling should email visiting assistant professor of computer science Debbie Perouli at depe(at)purdue.edu.
