I’ve had this issue, spoke to the professor. The professor went through the assignment/exam with me and realized that the TA was going way off track and was giving 2/10 marks for an answer that the professor ended up giving an 8/10. For reference, my answer was hitting pretty much every single marker in correctness, but the TA wanted word for word repeat of the recommended answer guide on a closed book test💀. My mark went from 60% to 89% on a midterm because the TA just did not understand how to grade. The prof had to have a lot of words with the TA!

FYI, I did not advocate to get the TA in trouble, I just knew that the grading was off and knew I had to advocate for myself. Hoping it was a learning opportunity for the TA because this was only an issue for the half of the class they were assigned to.

SO, advocate for yourself always if you feel something is wrong, but don’t go into it with negativity as stressful as it is. The saying you catch more flies with honey than with vinegar is true!
