There is an app in the app store called Perfect 36. This app contains 20 lessons on each of the four subjects covered on the ACT, there are over 1000 practice problems, 200 of the most common vocabulary words, and high quality videos that teach the concepts covered on the math section of the test.
This way, every student can have chance to prepare for the ACT. Our school out of a handful in the tri-state area was chosen to participate in a free month trial of the website.
Upon entering the website, you will be asked to log in. Simply use the username and password provided. The free one-month trial will end on 10/22/17. After the trial is over, if you find the app useful you can download it in the app store for a fee of $4.99.
