It is apparent that Reading Comprehension is your strong suit: your percentile ranking is the highest in this sub-section despite you spending the least time per question there. Critical Reasoning is almost the opposite.
Overall, I see that you spent more time on each question that you got wrong than on each question that you got right, on average. Moreover, the questions that you got wrong were more difficult than those that you got right. These 2 facts tell me that you struggled with difficult questions on the exam and consequently could not break into the 40's in Verbal.
You spent a lot of time on the first quarter of the section, presumably because it had several CR questions that you considered tricky. You did pretty well on Medium-difficulty questions, except for the last quarter when you were running out of time.
So basically, you have a decent, though not great, foundation in Verbal. You can answer questions that are easy or moderately difficult questions, but struggle with the more difficult questions, except for perhaps RC questions.
In order to get into the 40's range, you'll need to make significant improvement in Verbal, especially in Critical Reasoning. You'll need to learn how to answer any type of CR question presented to you, and do so efficiently. You'll need to do the same thing for Sentence Correction, but focusing more on accuracy first. At the same time, don't let loose on Reading Comprehension - you want to be able to replicate your performance on Reading Comprehension for sure!
Once you are at the near-40 level, keep in mind that you'll likely face question types that appear unfamiliar, and in order to answer these "strange" questions, you'll need to gain more experience with applying grammar rules as well as build a fundamental understanding of critical reasoning.
At this point, you probably won't find much use in new study materials; the resources that you have utilized are all great. Instead, I would recommend that you get a good tutor that can help you with these specific issues.
Hope this helps. Best of luck!
