Hi RB4U.
In verbal, you need to improve in both SC and RC.
For SC, you could mostly keep practicing, and fill any knowledge gaps that you identify as they cause you to miss questions. You should practice untimed for the most part, and any time you miss a question, your move is to figure out exactly why you missed it and address that issue so that the same issue doesn't trip you up again.
For RC, it may help to learn some strategies so that you know exactly how to answer the questions when you see them and execute well every time.
Since RC is one of your weakest areas, you may find the ideas in this post helpful.
