Double Major or Graduate Early

Hi everyone! I need some advice for anyone who is willing to give me their opinion!
I’m a freshman at SB and by the end of my Junior year here, I will run out of enough classes that apply for TAP.
Now that TAP doesn’t cover minors, my only options are to either double major or graduate early (possibly a year early).
I’m a physics major and I know I want to get a PhD in physics. The possible double majors I was considering were AMS (Applied Math and Statistics-- which I love), or CSE (Computer Science – which I find interesting and OK).

I would appreciate some advice. Thanks.
