Create an Online Course Self-study or Evening Classes out of PDF

What are the best options to create a nice online study for my students out of my PDF created distance learning and power point presented evening classes. I would like to combine both into one online system, with a possibility of learning the matters and training via multiple choice questions. Besides text a lot of graphics is needed to explain the matters as in the FAA’s pilot training manual can be seen… Thanks in advance for advising, Brgds Erwin Prins
