Any advice for a career changer? Moving from biology to business

As the title suggests, I’m changing my career from biology/research to business (ideally in marketing/analytics). I am beginning an MBA program in the Fall, but I want to get out of bio and into a business centered position ASAP.

Would enrolling in one of the Google/Coursera data analytics certificates in the mean time help? Or should I just continue applying until I hear back from someone?
