When you are presented with the tRAT quiz each answer of the question is show as a "scratchie". So if with your team you select an answer -unlike with the previous test you did individually, you get immediate feedback as to whether the answer selected is correct or incorrect. If the answer you select is incorrect, unlike the iRAT test, your team can try for another option. If the new option is still incorrect, you can continue trying until your team finds the correct answer.
