This is a detailed examination of conscience.
If you have not been to confession for a long time (many months or years), go through it slowly. You can bring this list in the confessional with you.
If you come to confession regularly (every week, fortnight or month), you need not go through the whole list each time. Pay more attention to your weaker points and habitual sins.
For each mortal sin, one must give a) the exact number of times or at least the frequency (for ex. once a month for 2 years), b) the circumstances which can change the nature of the sin (for ex. to steal in a church.).
For venial sins, it is good to give an approximate number of times.
A) MY FORMER CONFESSIONS
I have made bad confessions (lack of preparation, of contrition, or of a firm purpose of amendment) ... times
I have concealed some mortal sins because I was embarrassed... at what age?
How many bad confessions? How many resultant bad communions? Have I corrected those confessions?... When?... How often...?
I have forgotten to confess some mortal sins in subsequent confessions. How often? What were those sins? How often?
I have gone to Communion without fasting... voluntarily or involuntarily?
