·         The duration of the exam is 1 hour and 30 minutes.

·         Identify ALL sheets. This is critical, because the exam sheets will be separated.

·         Some questions are not the same in different versions of the exam.

·         The value of the question is presented in squared brackets, e.g., [1v] = worth 1 value in 20.

·         In the open-response questions:

• Read all paragraphs of the question before you answer the first one.
• Be objective and concise in your answer. Use only the space given.
• The exam can be answered in English or in Portuguese.

·         In the multiple-choice questions:

• Each question only has one fully correct option.
• If there is more than one correct answer, choose the stronger statement.
• A question has N options. In your answer, you can select one or more options. However, for each question, the grade is calculated given the options you selected, in the following way:
• • The correct option is worth the full value of the question;
  • Each incorrect option discounts 1/(N-1) of the value.
• Example:
• • For a question with N=4 options, you are undecided between two options, and select both: A and D.
  • Assuming the correct answer is A, then the grade is 2/3 of question value
  • (the right option A is worth 3/3 but the wrong option D discounts 1/3)
• Please write the answers of the multiple-choice questions in the table. This is critical, because
• all markings on the question text itself will be ignored.
• Write only capital letters (A, B, C, D, …) and inside the respective table cell.
