Ramadan Section: Studying?

Wa alaikum mussalam. I'm not familiar with any doa on this, and as I see what have been posted in this forum are good doas. But as what I usually practice in regard of this is just read a simple alfateha before you go to revise your books and then start reading them. After reading the book, I always try to write down whatever I have read without looking at the text. By doing so then you will know what you have missed and could remember what you have written. The rest is up to the o mighty god.
