Most bible studies involve discussions of a passage from the bible chosen beforehand. Generally, people have prepared for the study by reading the passage and answering some questions from a study guide. Some of the questions are factual. Other questions ask how you might apply the passage to your daily life. Yet others focus on your thoughts or feelings about what someone said or did in the bible passage.
Another form of bible study involves a lecture by someone, either a priest or knowledgeable lay person, with the opportunity to ask questions.
