Double majoring in MEB and IB?

Hey guys, so I’m originally majoring for MEB but i was lately thinking about IB due to many professors coming in to talk about it in my class. Is it worth it to double major in both IB and MEB? Or should I switch to the other? What are your all’s opinion?

Also is it good to take both german r5b and native american r1A during the summer in 6 weeks? or would it be too much reading and harder for me?
