Try it and see. Everyone is different. Some kids take months to ride a bike without training wheels others days. Everyone has their own schedule. And it depends on a number of factors. Do you use it everyday day. How many books you fully activate. How many books have you PhotoRead. For each person the breakthrough amount is different.
The only way to find out how long it takes you to become proficient at PhotoReading is for you to do it and see.
