University of Michigan Superscoring

Hi! UM is my dream school but i understand that my chances are low. Im confused by michigan superscoring as they look at everything and take everything into consideration. I studied hard for my first sat and got a 1940. I worked all summer so i didnt have time to study and forgot much of the information when i took the sat again in the fall. My writing bumped 60 points putting me at a 2000 superscore and finally in the writing range. However, my math and reading significantly decreased ( i didnt really take test well bc wasnt expecting to improve) to the low 500s. Would it be better to submit all my scores, or would admissions seeing a 500 be a turnoff? Please help!!!

Michigan does not superscore.

I would submit all of my scores.

The CR at mid 600 would be near the bottom 25%.
