Question 1

Reverse Plugging In: Not Sure In Which Direction To Go

Answer 1

If the answer you Plugged in doesn’t fit, POE it, and try to decide in which direction to go.

If you can’t make up your mind in which direction to go after 10 seconds, pick a direction and go.

Some answer choices do not need to be plugged in - Try to POE answer choices that don’t fit the problem before you Reverse PI.

The Reverse PI process within the question becomes faster and faster as you advance down the answer choices and embed the logical path in your mind.
