1st 90 days as team leader?

Is 1st 90-day guidance more than just "fit in" when you're leading a new non-professional team?

I'm a new club president in an MBA program, so my board is made up of peers (other students). I want to apply as many Manager Tools as possible, but I only remember a career tools cast about the 1st 90 days in a new job, as a direct.

What about leading peers in a school club setting?

Thanks, MT community!
