You still have a shot. I got in with very similar stats for the class of 2016, and I'm Asian. Just send your best ACT scores. So, if you got like a 31,31,31,31 on your first two ACTs, but if you get a 32,32,32,32 on your third one, I'd just send the third one. Pretty much, just send in whatever combination makes you look best. So, essentially, it doesn't matter how many times you take the test, just how many tests you send to Vanderbilt.
I'm not sure where you saw that range of 32-35. For the class of 2105, the range was 31-34. As seen on the admissions blog, this past year admitted students' scores were higher. I can't say for sure but it wouldn't surprise me if the range for the class of 2016 was 32-34.
I think you have a really good shot. I'd take as many AP classes as possible your senior year. If you can take more than 3, and you're only taking 3 then that is not a good thing. Nevertheless, I think you have a really good chance at getting in. If you have any questions, just message me. If there was anything I wish I had more of when I was applying to college, it was guidance and of course better test scores haha.
