You will find several helpful documents on this page. The first three--Grammar Rules, Punctuation Rules, and Mechanics Simplification--were created by Mr. Irby and are invaluable in preparing for the ACT test.
The flash cards are a combination of rules, considerations, and sample questions. If you choose to print these, which you may, the pages need to be printed front-back. For example, page two is the back of page one; page four is the back of page three. This is the only way to correctly match the squares because the right column of page one corresponds with the left column of page two.
