You need to time everything! Let yourself have the timed experience first, and then go back and take as much time as you need to rework and review before checking the answers. It's hard to assess your progress on untimed problems, because a problem you get right in 5 minutes is not a problem you have mastered.
Your performance is actually fairly even across the three verbal topics, although you are slightly higher in SC than in the other two. I mentioned CR/RC not because you are lower there overall, but because there is one core skill there--inference--that will win you a lot of points if you master it. You are really getting beat up there, especially on the RC side. Just to give you some perspective, on the last tests you missed more problems in Conclusion/Inference than in all of Number Properties! Still, there are plenty of things to look at in SC. I'd start with Modifiers.
By the way, I got all this data by running an assessment report based on your two most recent exams. Do you know how to do that? Go to your CAT exams page & hit Generate Assessment Reports. (Or just use this:
https://www.manhattangmat.com/assessmentreports.cfm) Check the boxes for all of the exams you want to include. You can combine them all, or just use the ones you feel are most representative. You can even choose a single exam. Then hit Generate, and you'll get a series of 5 reports. These are extremely important to study! Note that the last two are multi-page reports that break down your performance in each subtopic of each book. You can click on each one and see a list of all the problems of that type in the included exams. You can use the reports to narrow down topics for study, and then use these specific lists to study problems within each focus area.
Happy studying!
