Is a post bacc worth the money and time?

Omg that’s amazing she found a great opportunity! If you don’t mind I would love to hear updates! May I ask when she took the MCATs? I was initially going to take the GRE this summer but I realize that some programs require MCAT scores. I would like to take my MCATs this year however I’m afraid they will become invalid by the time I am done with a post bacc.
