If fractions are causing you some grief, then use your calculator to simplify, add, subtract, multiply, and divide fractions. You can also rewrite fractions as decimals. After you solve the problem algebraically, I suggest you check your solution graphically, using your TI Plus.
After you graph your functions, press the 2nd key and then the trace key and then select intersect to find the intersection point. There will also be problems on the ACT that will require you to solve systems of linear inequalities and find the points of intersection in the bounded region.
You can solve that problem algebraically and then use the Inequalities Inequalz app on the TI Plus to check your solutions. This app even provides the intersection point of the lines. On the ACT, you might see a problem like this:. Turn on the Inequalities feature by pressing the app key and selecting Inequalz. Then follow the steps in the video below to check your answer. Check out these test prep exam resources and product tutorial videos for additional tips. And, remember to check your email frequently for any updates or test center cancellations.

Cover the infrared data port on your calculator and confirm that your proctor has seen this modification.
Some later models of the TI shipped with an IR-data port for transferring information between calculators. These ports use light to transmit data. When the ports are covered, they are inoperable. Those are also high performing, fully-functional calculators that are great for the ACT. A scientific calculator will get you through the test. If your calculator has a rechargeable battery, ensure it is fully charged.
It would be incredibly stressful to have your calculator die during the test when you were prepared to use it.
