Online animation courses while studying at uni?


I’m currently studying 3D animation with a wide focus on all parts of the pipeline but I really want to focus on and get better at animating in 3D and do an online course. I have looked into Animation Mentor but I’m not sure the workload is too big to do both uni and AM at the same time so I hope to find a part-time online course.
Are there any courses you have tried or would recommend?
