ACTFlash - ACT Prep and ACT Practice

You can take 10, 20, or 30 questions that are timed for free and app tracks your percentage progress. For 40 or 50 questions that can test your fatigue, you have to pay.

This app is absolutely awful. Literally the first question asked of me on the math practice was about prime numbers, and I answered correctly. It was basically asking about prime numbers between 0-8, extremely easy stuff. To my surprise, the app said I answered incorrectly and the "explanation" stated that the ONLY prime number between 0-8 is 1. ONE! Anyone who has been to elementary school would know that a) 1 is not considered a prime number and b) 3, 5, and 7 are all prime numbers in between the integers 0-8. The fact that any respectable ACT app would publish a question easy enough for a fifth grader and then program the answer INCORRECTLY is beyond me. This app is complete trash, don't waste your time with it.

Fun, fast questions that time you so you can keep track of how fast you are going. It scores you at the end of your sessions so you can see how well you did and compare with your best score. Fun way to study.
