Some of those topics are:
- Preparation for the married life
- Differences between men and women
- Basics of financial planning
- Conflict resolution
- Religion
- Children & family planning
In other words, it's a seminar for marriage preparation (the long term). It's one of the church wedding requirements. At the end of the seminar, couples will receive a certificate (this is important).
The seminars are scheduled (in Tarlac City I think it's just once a month). It's best to ask and reserve for a schedule at least months or weeks before your church wedding date. The church staff would notify you of the time and date of the seminar (of course both you and your partner should be present).
