Each prep-pack can be practiced in 2 different modes. 

1. Step-by-Step Mode: 

Each question in this mode comes with a detailed explanation on how to solve the question. We recommend starting here and moving on to the Timed Mode once you feel comfortable with the material.

2. Timed Mode: 

This mode emulates the time constraints of the actual exam. The step-by-step explanations are only available once the practice-test has been submitted.
