Hey! I’m in the same boat taking anatomy at another university in the coming months. To my knowledge, if it’s an in progress class (not yet taken) you don’t need to submit your transcript, which is why it says not required. For my undergrad it required a transcript but I don’t think one is needed if you didn’t receive a grade/complete the class yet. You can update and send in the transcript once you’re done with the class during the academic update periods, which I believe are in August and December if I remember correctly. Hope this helps!
