before doing anything, I would recommend taking a PT to see how much you've retained from studying the lessons. If you like where you are, great. If not, push back! Honestly it really just depends on your own personal goals.

Also, even though you can score preview and cancel, do you really want to go through all the stress if your score isn't where you want it? I would personally just rather wait and take it once knowing I'd be more prepared. but thats just me!

If you're consistently going -0 on LG, I would skip them and just br LR and RC. I'm pretty confident at this point as well, so I just bookmark the questions I'm anything less than 100% certain about and BR those. If i get anything wrong that i didnt bookmark, then i also know i really have to look at that question in more detail to understand why I thought i was correct
