No, since the exam is adaptive, your question will be assessed as soon as you click "Next." Remember, each question is based on your previous performance in an adaptive exam. As you properly answer questions, the exam becomes harder. As long as you keep responding properly, you will see tougher questions. If you answer a question poorly, the questions get easier until you can answer them properly again, and this continues until the exam is over. Hence, you will not be allowed to return.
