I studied the first lesson carefully and got between 90 to 100 as my first grade.  

The next day before I studied Lesson Number Two, and this is very important, I read  Lesson Number One out loud before I began to study Lesson Number Two.  

On the second day I got between 90 and 100 in Lesson Number Two.  Before studying Lesson Number Three, I went back and reread out loud Lesson Number One, Lesson Number Two and then began to study Lesson Number Three.  I got again between 90 and 100.  My grade was usually around 95. 

 Before studying Lesson Number Four, I went back and reread Lesson Number One, Number Two, Number Three and then began to study Lesson Number Four.  I developed the habit of always reading the previous lessons out loud before studying the current assignment.  This is the procedure I established for myself when studying a foreign language.  

This continual daily review of previous lessons before studying the assignment made my study of French a lot of fun.  My grades from that time onward all the way through graduate level  never once, with one exception, sank below an "A".     If I can do it, you can too.

I always read all foreign language texts out loud for the simple reason that I need all the practice I can get in speaking.  I don't do this in my native language, only in the foreign languages that I am studying.  I attribute my joy at learning foreign languages and the success I have had with them to this way of practicing.
