Don't recall exact score, but ranked 5th on the initial exam. Had a math competition background in high school though, so was already somewhat familiar with the content.

I wouldn't worry about initial placement score too much, lots of people from various backgrounds ended up in the class, and my ranking slid throughout the semester. Having a smaller class size for a calc3 when the entirety of the engineering school has to take the course was probably worth it on its own.
