From the U.S. Bishops:
Before celebrating the Sacrament of Penance, one should prepare oneself with an examination of conscience, which involves reflecting prayerfully on one’s thoughts, words, and deeds in order to identify any sins.
There are various types of examinations of conscience but regardless of which one you use to prepare yourself for the Sacrament it should be rooted in Scripture; particularly, the Ten Commandments and Beatitudes. Below are a few examples of Examinations of Conscience that can help you prepare for the Sacrament.
From Bulldog Catholic:
A good Catholic examination of conscience can be a great help in making a new start in the life of faith.
We use an examination of conscience to help call to mind our sins and failings during a period of quiet reflection before approaching the Priest in Confession.
It’s important for a good Catholic examination of conscience to be thorough. This will help you to consider what sins you are guilty of and make you aware of sins you might not realize as sins. It’s also a chance to develop your conscience. This is a critical aid for any Catholic.
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 matters of this list and honestly reflect on your behavior for each.
• You may want to take this list or some brief notes (in secrecy to avoid scandal) to Confession to help you remember things.
• Remember that a mortal sin is committed when :
1. Full Knowledge that the act (thought, word or omission) was contrary to God’s will (sinful) is possessed by the offender;
2. Full Consent (with intentionality; i.e., not forced) is held by the one committing the sin;
3. Grave Matter (anything under the Ten Commandments and the Precepts of the Church) is the circumstances of the sin. Not to belabor the point, but, there is a difference in grave matter between stealing $10 from a friend and stealing $10,000 from an orphanage. If any of these three conditions are not met the sin is to be known as venial. It is a very good idea to confess venial sins as well, since these sins, like all sin, offend God Who deserves all of our love. Confessing venial sins helps us to be more sensitive to God and more faithful in our love to Him.
If all three conditions are met the sin is known as mortal.
Remember, ALL mortal sins must be confessed according to the kind (what type of sin) and the number of times committed for a valid confession. If one willingly withholds and conceals a sin in confession it is a sacrilege (which is another mortal sin), and it invalidates the absolution. Do not worry! Do not be afraid! Jesus wants you to tell him your sins with honesty and courageousness that he may remove the hurt from your heart and soul. Do
not further steep yourself in sin by concealing sins in confession.
Also, it should be noted, the priest is bound under pain of grievous mortal sin and excommunication, if he ever reveals anything said in the confessional. No matter how grievous the sin, do not be afraid. Admit your failings openly and God will grant you His sweet gift of forgiveness.
