I just uploaded video explanations to all of the math questions in the 2015 June ACT Form 73C Test.

ACT Practice Question: Quadratic equations and graphs
Try this ACT math practice question on quadratic equations and the graphs of the corresponding parabola:
If the parabola $y=-x^2 + bx – 8$ has its vertex on the $x-$axis, then $b$ must be:
- $\quad \textrm{a positive integer}$
- $\quad \textrm{a positive or a negative rational number}$
- $\quad \textrm{a positive rational number}$
- $\quad \textrm{a positive or a negative irrational number}$
- $\quad \textrm{a negative irrational number}$
ACT releases Official Practice Test: 2015-16 Form 72C
ACT just released the official practice test for the 2015-16 year. The practice test is based on the June 2014 Official ACT test, Form 72C. However, not all questions are identical. For example, in the math section of the practice test, only 36 of the questions are present in the June 2014 ACT test. Here is the link:
ACT Practice Test: 2015-16 Form 72C
This also happens to be the first time that the practice test released by ACT is from a recent administration.
Please note that ACT uses this generic link to post practice tests and the link in the future will point to an updated test.
