To make an examination:
Set aside some quiet time for reflection. Start by praying to the Holy Spirit, asking for help in making a good examination to prepare for Confession. Read through the items on this list and honestly reflect on your behavior for each item. If necessary, take this list or some brief notes (keep them private!) to Confession to help you remember things. A Catholic examination of conscience traditionally follows the outline of the Ten Commandments and the Precepts of the Catholic Church.
