It may be helpful for some considering seminary if I briefly describe a typical week's worth of work for an introductory class. Here was last week's assignment from Introduction to Reformed Theology, a 3 credit hour course at Greenville Presbyterian Theological Seminary:
1. Attend class (for me, listen to the audio)
2. Make an outline of three chapters in the Westminster Confession of Faith
3. Memorize four questions and answers from the Westminster Shorter Catechism
4. Read 3 hours in John Calvin's Institutes of the Christian Religion
The total time spent each week is about 8 hours.
