msircha,
Thanks for your question! Let me start with a direct answer to your question: yes, it is absolutely common to have some variability in your practice test results as you progress in your studying. This can come from a couple of factors:
1.) If you are working your way through the PowerScore concepts, the truth is that some of them ask you to do things a different way than how you may have been doing them before. This may not feel as "natural" at first, and it is normal for students to struggle - but the goal is that it pays off in the end. An example of this could be diagramming conditional reasoning problems...at first, this can take a long time to do, and may make it harder to get through all of the questions in a section. But after a while, it will actually speed you up as it gives a framework from which to answer the questions, and also increases accuracy. So this could be happening with your scores.
2.) You note "studying fatigue" - that is an all-too-common problem! Many students get burnt out, especially if they've been studying a long time and/or aren't seeing increases. Sometimes taking a break or slowing down studying can be more useful than devoting more and more time. I would think about dialing back the hours a bit and seeing if that doesn't help the burnout feeling.
3.) The last thing to note is that there is simply an element of luck and chance involved in any individual LSAT section (and overall LSAT). What I mean by this is that while the makers of the LSAT generally try to make each test section roughly equally difficult, they don't always perfectly succeed; and even if they did, not every section has the exact same number of questions of each type in it. Here's a great article from Dave about the role that luck plays on the LSAT, which applies to your practice tests as well:

Hope that helps, and let us know if you have any other questions!
