Hi James and Haley! Haley, thanks for providing some nice tips.
It's extremely normal for people to get more questions wrong in the second half of an LR section. As Haley points out, part of this can be a stamina issue. To that end, she's exactly right that there's a couple things you can do to up your stamina. Practicing untimed LR for long stretches of time, taking full timed practice tests with 5 or even 6 sections, doing mental focus exercises, maybe doing physical exercise such as running, making sure you've got a consistent sleeping/eating/schedule, etc.
But aside from stamina, the bigger issue is that the questions simply get harder as the section goes on. Here's a blog post about it:

So again, it's very normal to get more wrong in the latter half of an LR section. It just means that you're bumping up against more challenging questions. To that end, it's very important to work on implementing all of the methods we talk about here on the Forum, or in our Course Books and Bibles. On many of the easier questions at the beginning of LR sections, you can sort of "intuit" your way through a problem. But as the section goes on and the problems get harder, you need a consistent and structured approach to all 13 of the LR question types in order to succeed. So keep honing those question types! Pore over the PowerScore Bibles, and post here in the Forum for any specific questions/question types that continue to give you trouble.
Hope that helps!
