You have a really good chance in my opinion. Test scores wise you seem competitive but I think you lack in ECs a little bit. I would def not be surprised if you got in, but if you don’t its probably just because of insane competition and ridiculously low acceptance rates. I would say a high match or low reach. Good Luck!
You have a good chance of getting into Brown, but like Ballerina said it’s a reach for everyone. Keep in mind that it is Brown after all and no one is guaranteed in. Best of luck though.
For an unweighted GPA to exceed 4.0, the scale itself has to exceed 4.0. If the highest theoretical grade you can receive in a class is 4.33 (the A+ referenced in the above post), then the unweighted GPA would be 4.1/4.33, not 4.1/4.0. There are also schools that use a 5.0 scale. That’s all clarified in the school profile.
