What’s your STEM aptitude? This test assesses your aptitude for solving the types of problems that arise in science, technology, engineering, and mathematics (= STEM). You have 20 minutes to complete this test. Where an answer requires more than one word or number, separate them by single spaces. Express fractions in lowest terms using “/” as separator. This test requires no specialized or technical knowledge. Once you answer a question and hit “next,” you cannot go back. All questions and answers will be reviewed at the end. Have pencil and paper at hand. READ THESE INSTRUCTIONS AGAIN. Good luck!
