Confession

The confessional is located in the main chapel, if you enter from the large wooden doors that face campus it will be to your left once you are in the chapel. In the back, there are three doors, the middle one is where the priest is, and then you can choose the right or the left for either face-to-face or through a screen (the doors are labeled). There is a light above the door that indicates if it is empty. If one of the lights is red that means someone is in there, wait until both are green and then you can go into the side you choose.

Prior to going to confession, an examination of conscience can help us to recall where we've fallen short. They are usually a list of questions to consider that relate to the commandments or Church teachings. It is important to remember that when reflecting on past sins there is a broader understanding of what they could be beyond the literal words of each commandment. The fifth commandment says "You shall not kill" (Lev 20:13) and this commandment can be understood to mean more than just not killing others, this could included willfully harming others or being reckless with your own wellbeing.  
For an examination of conscience you can visit this website or there are pamphlets available near the confessional.

Before confession make an examination of conscience and have in mind the things you will be saying. After entering the confessional (either face-to-face or through a screen), you will start by saying the sign of the cross out loud and then "Bless me, Father for I have sinned. It has been [length of time] since my last confession." After this you can say your sins; you should be specific, but you don't need to tell a story or include every detail surrounding a sin. Once you are finished listing the sins you can conclude with "I'm sorry for these and all my sins," this also helps the priest know you are finished. The priest may say something or ask questions and after he will give a penance. This is something you are to do after, it could be a prayer or an action. Next, you will say an act of contrition. This prayer can be found in the pamphlets or you can offer one from your heart. The priest will then pray the prayer of absolution and at the end you will do the sign of the cross and say amen.

No! The seal of confession is a very serious thing and a priest will never repeat anything that's said in the confessional. Even in the case of a crime or legal matter a priest will not and cannot be compelled to speak about something from the confessional. Priests also cannot use knowledge they've gained from the confessional in any way (Catechism 1467). If a priest were to break the seal of the confessional they would be excommunicated from the Church. The secrecy of confessions is a very sacred thing that is taken very seriously. 

The Church teaches that Catholics should go to confession at least once a year, but it is recommend to go as needed. It is necessary to go to confession prior to receiving communion if you are in a state of mortal sin. (CCC 1457) 

All sin is wrong but the Church makes a distinction that some kinds of sin are more damaging to our relationship with God. Mortal sin puts a severe break in our relationship God as we've chosen to turn away from Him, while venial sin wounds the relationship. It is also a sin to receive communion while aware of having committed a mortal sin. All sin harms our relationship with God and regular confession can help our relationship with God grew and help us resist temptations. 

More can be found on sin in the Catechism 1854-1864 or here.
