How to prepare for the act exam
Learn the format of the exam.
It is important to understand how the exam is structured so that you can master all of its sections. The act has four sections with an optional writing section as well.

Choose from: (a). The section consists of instructions for the acceptance exam, a writing section for the test date and a verbal planning section : Pre-test. This section is meant to be fun in itself and can teach you about the material. (b). The english section covers punctuation, grammar, proper word usage, sentence structure, and style. Vocabulary is not a big component of the act english section. (c). Set up a study group to test each chapter before the test and make sure those chapters don't need to be explained more than multiple times in class. Prepare for the typing and problem sections if need be. (d). Check with your exam organization to determine which sections you need to cover during the test. You will have a summary of the coursework, additional lab work, and extra readings from your professor.
(b).
