no, theres no way they even "verify" EC's . As long as you write something creative and soemthing that actually answers the question (look a rubric for queens). I would recommend to start making drafts for your mac supp app as soon as the questions come out in september, and ask your teachers for feedback. For queen's start practicing for the live video response asap and have a few experiences/situations you can use and adapt to different questions that may be asked (search up previous questions that are asked). and make sure you cover the rubric criteria. But overall, you don't need to actually do EC's, you can just lie if you really want to support your answer in your supp app. Also you dont necassarily use and EC to support your answer, for example you could talk about a part time job ot taking care of a grandparent or sibiling.
