ISAT comprises 100 questions and you are given 3 hours to complete the test. The test is presented as Units, each one with a piece of stimulus (text, cartoon, graph, diagram, etc.) and multiple-choice questions that directly relate to each stimulus.
The testing time runs for 3 hours (180min) and there is a timer in the top right-hand corner of the screen.
Test questions come up on the screen one at a time. A "unit" is a set of questions based on the same stimulus material. There may be up to five questions in a unit, and the stimulus material will be repeated for each question.
You answer the question by clicking the radio button beside your chosen option, and navigate using "Next" or "Back" buttons at the bottom of the screen.
After Question 100, the list of question numbers and your responses appear, and you can check and revisit any questions.
When finished, you must press "Submit".
If you are still working when the time expires, the test questions and the review page will stop appearing when 180 minutes is reached, and your responses will be automatically submitted.
