Chance of getting in Johns Hopkins

Hi guys. I am a international student studying in an American highschool. My dream school is Johns Hopkins. Right now, I have a decent sat score with a super score of 1540. My TOEFL score ia also pretty good, 113 out of 120. But my GPA bothers me a lot… I only have a weighted 3.8, and a unweighted 3.5. I transfered to another school during my sophomore year, and I really messed up my grades back then. What’s my chance of getting into Johns Hopkins with these stats? I know it might be really hard to get in with my 3.5 unweighted gpa… but what can I do to make up for it
