The exam will become available in the Quizzes section on April 19th at 12:30pm and will disappear on April 20th at 12:30pm. This does not mean you can see the questions without starting the exam.
You can only see the exam questions once you start the test. From the moment you press “Start” the clock starts ticking and you have two hours to complete the exam. Please make sure you have a good, stable internet connection when you sit down to start the test. Neither you, nor I for that matter, will be able to pause it, rewind, or restart the clock.
