You can sign up now to take the pilot, 6.002x Circuits and Electronics, which is based on a core electrical engineering and computer science course taught to engineering students on campus.
Here's how it will work:
To access the course, registered students will log in at mitx.mit.edu, where they will find a course schedule, an e-textbook for the course, and a discussion board. Each week, students will watch video lectures and demonstrations, work with practice exercises, complete homework assignments, and participate in an online interactive lab specifically designed to replicate its real-world counterpart. Students will also take exams and be able to check their grades as they progress in the course. Overall, students can expect to spend approximately 10 hours each week on the course.
Check the course description to learn what physics and math you need to be successful, watch a short introductory video, and enroll. The course, which runs March 5-June 8, is free but you must register and complete the assignments to earn an MITx certificate.
Regarding MITx Certification:
If you successfully complete the course, you will receive an electronic certificate of accomplishment from MITx. This certificate will indicate that you earned it from MITx's pilot course. In this prototype version, MITx will not require that you be tested in a testing center or otherwise have your identity certified in order to receive this certificate.
