Stop Changing Your CAT Mock Strategy Randomly: Use One-Variable Experiments

Mock 1 goes badly.

So you change VARC order.

You also scan DILR differently.

You reduce QA attempts.

You start taking mocks in the morning instead of evening.

Mock 2 improves.

What worked?

You have no idea.

Treat strategy like an experiment

A useful experiment needs:

  • a baseline
  • one change
  • a metric
  • a result
  • a conclusion

    CAT strategy should work the same way.

    Step 1: choose one repeated problem

    Examples:

    • VARC accuracy falls in the last 10 minutes
    • your first DILR choice is repeatedly poor
    • too much QA time disappears before Question 10
    • one bad section affects the next
    • easy QA questions remain unseen

      Choose one.

      Do not repair the entire CAT paper at once.

      Step 2: write a hypothesis

      Weak:

      > “I will improve QA.”

      Useful:

      > “If I use a strict first pass, I will see more QA questions and miss fewer easy ones.”

      Now the change can actually be tested.

      Step 3: choose the metric before the mock

      For that QA experiment, track:
