Among non-Catholics there is a fair (or maybe unfair?) amount of misunderstanding regarding the Sacrament of Penance at the confessional. All but ONE of the following are at least broadly true: which is NOT?
When someone has confessed their sin/s, the priest will pronounce a formal prayer of Absolution and set a Penance (recommendation of good deeds to be done to confirm an improved attitude; or at least, several further prayers to be repeated)
Confession is permissible in three ways: privately (probably weekly, soon before Mass); occasionally at Parish Penance Services, such as during the penitential seasons of Advent and Lent; and rarely, through General Confession and Absolution in circumstances where individual penance is impracticable (e.g. during a major public emergency)
Confession of mortal sin is essential, and of venial (somewhat less serious) sins is encouraged; 'imperfect contrition' is when the sinner confesses out of fear of God's punishment, rather than from shame. It entails total secrecy: the priest who hears the confession, even of mortal sin, is bound never to divulge what he has heard, even to (for instance) the police who may be following up a serious crime
(Choose this Answer if you believe all the other three are true)
The baptism stipulation (Ans.2) is genuine but not exclusive, in that baptism into several other churches is acceptable: within the past 20 years or so, several alienated ex-Anglican priests (for instance) have converted en-bloc to Rome by special dispensation ~ sometimes bringing entire congregations across with them ~ after differing with the 'C of E' over gender issues such as women priests or the sanctioning of marriage between same-sex couples, divorcees or whatever.
Further to Ans.3, a first degree is a marker that someone has a trained and capable mind, potentially able to assimilate all the complex information needed for priestly ministry; but the seminary will then provide not only that information, but also the crucial 'soft' pastoral skills of dealing with everyone from committees to the sick and those in all manner of need
