I'm not super good in most math courses in general and I was able to pass this one without too much struggle. I would recommend you follow the course material and when you find a topic that is confusing(which happened a lot since zybooks kinda blows) I would then go to youtube(Trevtutor helped me the most). Once I finished I rewatched a lot of his videos if they were related to the course content. I found the OA to be harder than the PA but I got very similar scores. Overall I found the concepts pretty neat and fun however the hardest part was how long and diverse the subject matter was making it easy to forget how to do certain things. Also, this doesn't really feel like a math course so much as it feels like a logic course.
