Reviewing is actually the most important part of the process! I'm glad that you're reviewing in so much depth. You'll have a much deeper understanding of the test than students who just skim through wrong answers and click "show explanation."
Here's what I think you should do when you finish a CAT:
1. Run an Assessment report on ALL the CATs you've taken:

- In your Assessment Summary, you can see you accuracy percentages in PS v. DS, and CR v. SC v. RC. You can also see timing, average difficulty, etc.
- In "Quant by Topic," you can see breakdowns of exponents, quadratics, etc.
2. Run an Assessment Report just on the MOST RECENT one:
- see if you've improved on anything since previous tests
3. In your most recent test, start with your WRONG answers in problem topics / question types.
- redo the problem before looking at the answer
- ask yourself: did I identify the concept? Did I think it through before solving? Did I have a plan? Did I execute that plan well?
- then read the explanation
4. Log your errors into an Error Log:

5. Review RIGHT answers.
- Was it a lucky guess? If so, redo the problem.
- Ask yourself: could I have solved it differently? If so, try it.
- Did you learn anything from that problem about how the test behaves?
6. Flag to yourself any topics that need further review, and begin to review those.
This process
should take a good deal of time. Just make sure it's not all that you're doing! You also want to be doing topic-specific practice to build your understanding of the variations of questions within a topic.
