What are some general test-taking tips for the reading test?
You should mark up the passage as much as possible, while still reading rather quickly. Find different symbols to identify different areas of interest, such as circling names, underlining key terms, bracketing important lines, and numbering pieces of evidence. Most importantly, think like a test-maker; try to anticipate the questions as you are reading.
How do you approach the English questions related to active and passive voice?
For the ACT, active voice is always preferred over passive voice. To identify passive voice, determine if there are extra "helping verbs" and if the subject is no longer doing the action in the sentence. The subject should be doing an action, not being acted upon or receiving an act.
How do you set up and solve a system of equations?
First, use the word problem to set up 2 equations that use 2 different variables. Then, use either the elimination or substitution method to solve. For elimination, multiply one equation by a constant so that when you add your two equations, one variable is eliminated. Solve for the other variable and then plug back in. For the substitution method, solve for one variable in terms of the other. Plug that into the other equation. Solve for the first variable and then solve for the second variable.
