The Official ACT Prep Guide 2018: Math video explanations

This page provides video explanations to all of the mathematics questions that are part of the three practice tests in The Official ACT Prep Guide, 2018 Edition released in May 2017. The three tests in this official guide are a mix of questions taken from April 2015 ACT (Form 73G), June 2015 ACT (Form 73C), and the five tests that were published in the previous edition of the Real ACT Prep Guide, 3rd Edition. I would recommend students to skip buying this guide, and instead use the full April and June 2015 ACT tests, and combine it with the five tests that are in the Real ACT Guide, 3rd Edition.

Practice Test#1 (Form 16MC1): Official ACT Prep Guide 2018

Practice Test#2 (Form 16MC2): Official ACT Prep Guide 2018

Practice Test#3 (Form 16MC3): Official ACT Prep Guide 2018
