You are required to click "Yes, I accept/agree" on the NDA screen to start your exam within 2 minutes. If you click "No, I do not accept/Do not agree" deliberately or by mistake, you will be prompted to change the option on the next screen. You are also reminded at the end of 1 minute if you have not yet accepted the NDA. However, if you still click "No, I do not accept/Do not agree", or timeout despite the reminder the exam will end. You will not be able to resume exam. Test centre staff will not be able to do anything and you will lose the exam attempt as well as forfeit the exam fee.
