The weekly studies were designed to provide a discipleship tool that can work in person or electronically. It is designed with the busyness of life in mind, so that no one can say, "I am too busy for discipleship."
 
One possible format would be as follows:

5 day plan
Day 1:  Email the weekly scripture and questions.
Days 1 and 2:  Read verses and pray that God will speak to you through these verses. 10-15 minutes each day.  
Days 3 and 4.  Read verses and answer questions.  10-15 minutes each day.
Day 5:  Discuss scripture and question in person or by phone. 15-30 minutes, or as long as you have.
You have 7 days each week to get in these 5 days.
