In each game, the contestant (an adult) is asked a series of 11 questions, spanning ten subjects (such as Animal Science, Spelling or Math) taken from textbooks for first through fifth grade students. Each question is associated with a grade level; there are two questions per grade, from first to fifth. The player can answer the questions (either true/false, a three-answered multiple-choice question, or short-answered question) in any order; contestants lock in their answers by pressing the button on the podium, and each correct answer raises their cumulative amount of winnings to the next level (see table at right); after answering the fifth question correctly, they are guaranteed to leave with at least $25,000. If the player correctly answers the first 10 questions, they are given the opportunity to answer a fifth-grade bonus question (sixth-grade in the 2015 revival) worth $1 million (see "Million Dollar Question" below). The prize money and the board layout is as follows:
