Any sort of experience in low/no viz, entanglement, self control will carry over to a degree. but it won't guarantee a pass or you will be perfect. You can ask any of my firefighters that have failed my PSD course. They all assumed that scuba and SCBA would be the same in no viz/things going wrong sort of way. Long story short the majority of them were very humbled and had more than a few wide eye moments. And these are guys I would have back me up anytime/anywhere in a building fire.
The hardest part of that course for me to teach someone is how not to panic, some people it's completely natural to be calm and think through every decision, for others its a skill they will never learn. for those people, they don't pass. (This goes for every class I teach from OW to PSD to solo)
But there is way more to the solo course then just everything going wrong and figuring out how to fix it. The course not only covers not panicking and how to get out of trouble but how not to get yourself in that trouble in the first place. Like others have said if you take the course from a good instructor you will learn something. Is learning (even if it's just one trick) worth it to you?
I can absolutely guarantee that if you went back even years and many dives later and take an OW diver course with a decent instructor you might even learn something new.
When it comes down to it, it's money. It's a few hundred dollars and you have probably wasted more than that doing something that doesn't matter as much.
