I don’t think most of these people know what they are talking about. I would personally use parchment.com or Naviance to view actual acceptance/denial scatterplots to determine your competitiveness since your situation is pretty unique. Keep in mind that scores rise every year so you can’t trust those results wholeheartedly either. Let me know the results!
Also, you’re currently a junior right? This is your most important year; keep those grades high and you can possibly raise your GPA to 3.6 this year and to 3.65 by second semester next year.
