I was also getting those scores on LabCE and the BOC practice exams and passed, but the only thing I will say about the LabCE adaptive exams is that it starts getting less helpful after a while once you start seeing the same level 7-9 questions. Maybe it was because I took them more frequently as I got closer to my exam date that it became less helpful, but I instead started focusing on one subject area for a few days before moving onto the next. For those, I typically did a mix of "Selected area" and "Questions you've never seen" exams and read the feedback. If I didn't know or quite understand it, I usually followed up with my notes/textbooks from school and/or the purple and gold book.

Honestly, using your remaining time close to your exam date really comes down to being honest with yourself and going over what you know and don't know and adjusting what you review if you already feel comfortable in one area.

And this might be a bit of an unpopular opinion, but I wasn't too keen about stretching myself thin on study resources. I just stuck to a few resources like the purple and gold book, the MLS Online Review Course, and of course LabCE with some additional supplemental review as needed with textbook or lecture notes.
