Review the Daf. Etch it in stone.
In his Daf in Review series, Rabbi Schwartzberg uses his uncanny ability to synopsize the central discussions and conclusions of each Daf in 4-7 minutes/7 minutes or less..
Solidify the points of the Daf in your mind; Engrave them in your memory forever.
Now, in less than 7 minutes with Daf Hachaim you can have a full Daf in the palm of your hand.
