It doesn't matter in what order you do the assignments for that week. You just want to mix things up in different study sessions (ie, don't do only quant for 4 days and then only verbal for 3 days). (Love that you used the word interleave, by the way!)
And it also means interleaving activities. Read a chapter, try some end-of-chapter problems, go to Foundations of Math or Verbal if you think you need it for some topic (and if you have those books), come back to the main chapter to try or re-try problems. When you get through the several quant chapters assigned, try a mix of questions cutting across all 3 (or however many). Ditto when you're trying OG problems - first try a couple for just that chapter, but then mix it up.
And come back to chapters periodically. Look at a section header or the name of a grammar rule or whatever, and then look away and see whether you can articulate out loud whatever you're supposed to know about that thing. Or if, as you're learning something, you realize that this is harder or you're not entirely sure you're getting it / going to remember it, revisit it 2 days later and 4 days later. Basically, give yourself multiple exposures to the material - that essentially gives your brain a chance to make more memory connections, so you'll learn better.
Finally:
I want to cover as much of the books as I possibly can before the test
I would recommend adjusting that goal.
Be a smart business person: you want to do what you need to do in order to get the score that you want to get. Beyond that, you don't really care about learning every last detail that could be tested, right? (I sure wouldn't!)
Also, because of the way the GMAT works, you want to be pretty good across most topics (ie, be more of a generalist) vs. being amazing at some things but bad at others (specialist). So first get a good grounding across most topics (with the exception of your biggest weaknesses), and then see where your practice test scores are. Then see what you need to do from there to get to the score you want. If you don't have to do it
all, then why bother?
