Welcome to Zichru, a memory-focused program designed to help Daf Yomi participants retain the daf for the long term. It combines three different strategies to tackle the Daf Yomi memory challenge; Perek Learning Maps that provide big picture overviews and place the daf in context, Daf Simanim that employ a memory technique to remember three major topics on each daf and ongoing coaching on memory and mastery. Together they enable users to review a masechta daf by daf by memory, locate the daf for numerous topics almost instantaneously, and systematically manage and hold onto what they've learned in Daf Yomi.
