Any experience with IB Theater (HL)?

My D is going full IBD starting next Fall. She just chose her courses and has to confirm in May. She decided to do 4 HLs, including HL Theater. Her older sister took the same courses but with HL Art instead of Theater. How much of the Theater curriculum is performance? She is extremely interested in analysis of written and performed plays and also play writing and directing but doesn’t love performing. Thanks in advance.
