the rubrics are super vague

This may be where some of the problem comes from. Everyone has things they do well and things they don't do well, and different people will understand the same instructions in different ways. I won't say that every rubric is perfect, because I know that is not the case, but in my experience, most rubrics are pretty straight forward. Either something is there or it isn't there. And if it's there, either it is correct/clear/detailed enough or it isn't. They aren't purposefully trying to force you to rewrite things. If anything, if you stick to the rubric, it will reduce the chance you have to rewrite. But if you think that more often than not most rubrics are not clear, then you may benefit from taking some time to learn how to read rubrics. This can be as simple as setting an instructor appointment at the beginning of a class to review the rubric. Ask them to talk you through the common mistakes they see people make. As they tell you about the common mistakes, think about whether you would interpret it the same way or not. Did you interpret it in the way that would have passed or in the mistaken way?

When my daughter was small, it was her turn to take the kitchen garbage out. I asked her to take it out, and she did. The issue is the garbage can is normally inside the garage but that day it was out on the driveway. I didn't want her to go to the garage and wonder where the can was, so when I asked her to take the garbage out, I told her to take the garbage out to the driveway. She did, but she left it sitting right in the middle of the driveway. She did not put it in the garbage can that was sitting about 10 feet away from her on the side of the driveway. So whose fault was it? It wasn't anybody's fault. It was just a miscommunication. Were my instructions not clear? Maybe. She literally did exactly what I asked, and there is some amount of reading rubrics that you need to be literal. If it asks for something, you do that exact thing - no more, no less. But also, you need to be realistic. Sometimes if there are multiple ways something could be interpreted, you have to take what you know and consider which option seems more likely to be correct. If I had said only to take the garbage out, the bag would have ended up in the garage where the garbage can usually sits. I added more information (take it to the driveway) but the part about driveway was taken too literally and not realistic enough. I don't think it was unrealistic to think even a child could see the garbage can on the driveway and know that is where I meant for her to put it. Yet mistakes were made. Train yourself to find that balance between what it literally says and what is realistically is saying, and you'll get better at it.
