Will my big 4 internship offer get revoked?

Hello!

I am a senior accounting student at a Big 4 target school. This semester, I landed a core assurance internship with a Big 4 firm in Boston. I'm really excited to start working/starting my CPA prep.

This semester, I decided to take all of my core accoutning courses at the same time (Tax, Audit, Int II, Information systems) alongside 2 electives. I really underestimated the work load, and quickly got overwhelmed with work. My GPA before the start of the semester was 3.4, but I received 2 C's in Int II and Information systems. My GPA dropped to a 3.2. I'm a little anxious at the possibility of my offer being revoked. Should I  be worried, or am I just over reacting? Thanks!
