If I’m understanding your question correctly, you’re wondering if having a good pace in Critical Reasoning will help to improve your pacing in reading comprehension.
There are two ways of thinking about this.
Having a good pace (average of 2 min) on CR problems gives you more time for reading RC passages and answering questions. So if you have some strengths in CR, you should certainly lean on them.
On the other hand, moving fast in CR doesn’t necessarily translate to moving fast through RC passages and questions.
If you have speed in CR but not in RC, you may find it helpful to reflect on what helped you get fast at CR. Often, it’s some combination of:
- Learning the structural patterns of a short passage so you can digest it more quickly
- Knowing what’s important to understand and what’s not
- Quickly identifying common wrong answer patterns
- Knowing each question type deeply
- Having an effective system for reading and/or taking notes
Those same tools are the key to efficiency in RC, so you can use them as a starting point to figure out what you need to work on first.
A solid overall time management strategy for verbal helps, too. You can find one in this article: Everything You Need to Know About GMAT Time Management.
