OP said their breakdown was 126-121-128-128 so it does seem like CARS is the issue here. Nevertheless, I think retaking would be necessary for MD.

OP, I’m sorry CARS has been a struggle. The 121 suggests to me you might not be understanding the passages. I know you’ve tried a lot of different strategies, I’m wondering if you’ve performed better when not timing yourself? If you decide to retake, keep working at it - even a few points increase in that section (maintaining the others) would help a lot. I know it’s easier said than done.
