Why don't I try to actually answer you......
It's a little different. The main difference being that the time management and the pace of the course is a bit more on your side. Yes, read. Yes, study. But more than that , try to interact as much as you can in discussions with the class and the instructor. A mark of a good hybrid course is always one that has an active and responsive instructor, and an active roster of students willing to discuss learning points.
If you don't find these things, look for ways to expand upon different subjects on your own through trusted sources. This recent uptick in quality online (free) resources for EMS has really been great. As a basic, your most important skill to develop is the ability to assess, assess well, and paint a picture for the handoff. THe o2 and the c-collar stuff could mostly be taught to anyone. The questions you ask a pt are really critical as you are the gateway to higher care. Depending on your situation (rural or urban) you may be the authority for a good while so know your stuff. Envision answers to your questions and what that would mean for you in that scenario.
I don't take notes. Not that you shouldn't, but I just never found them useful. I see so many people "blindly read" and "take notes" and really have no idea how to apply the information. The point is, it is important to also know what kind of learner you are. Visual, tactile, auditory? And then see how you can best apply that knowledge while you are in the class.
A lot of good resources on this forum too. Ignore the naysayers. You will be fine.
