That all depends. People have done it as quickly as a week, some people spread it out over months. The more time you have, the better since you have more flexibility and options. The academic portion takes about 6-8 hours, the pool is usually around 6 hours total, and the open water portion requires 4 dives that are usually conducted over two mornings (most places do 2 dives at a time).
