Prepare for a test using a study guide by first reading through the entire guide. Seek out practice tests online and go through them with the study guide open nearby. Answer as many questions as possible, and make notes of more difficult information in the study guide.
Try to summarize each main section of the study guide into a few key facts. Expand on any knowledge of these facts using course books or other informational material provided, or seek out additional information online.
The food handler's safety test includes a lot of information involving safe temperature zones. All meats have different safe zones, and it may be helpful to make a table of this information to memorize. Be sure to commit the most common bacteria, fungi, viruses and parasites that can contaminate improperly stored or cooked food to memory. It is also important to become familiar with the dangers of sick people handling food.
Make a personal quiz that covers any information that continues to be difficult to remember. If necessary, break the quiz questions down into groups based on subject matter. Attempt to complete the quiz without referring to the study guide or any notes, and then grade it. Consult the study guide and any additional notes, and repeat this process until all troublesome information has been committed to memory.
