GPA dropped, will firms rescind my offer?

2L here. First want to disclose I am NOT in T-14 school.

I am currently debating between a law firm (big law) and an accounting firm (big 4). I lucked out on my jobs with my interview skills and experience that I was able to get two offers. However, I am bad with law school. My GPA dropped even more this semester, making my GPA drop from a 2.99 to a 2.91. Big law requested my transcript when I applied, and will again. Accounting firm didn't, but they said they will ask during spring semester (on offer letter says "required overall GPA is a 3.0. Falling below a 3.0 will impact your future employment."). Will they rescind my offer? Just scared.
