Jeopary-style review game

Finals for first semester will be at the end of January, and the biology final will be comprehensive. Today I prepared a Jeopardy review game for the students. The categories were "Ecology," "Acids & Bases," "Respiratory System," and "Health;" all of the categories except "Health" will be included on the final. I added in this category to get a feel for what they know. Overall the game went well, the students liked this review format. From this mini review, it seems more people in first hour will have difficulty with the final; they had difficulty with some of the questions. Second hour, on the other hand, thought my questions were too easy which is a good sign that they are prepared. Second hour also wanted a round of double jeopardy and final jeopardy, which I may include for the full review for the final. I gave both classes the option of negative points for a wrong answer or no points for a wrong answer; they chose not to receive points for a wrong answer. The game was played in groups and the group with the highest point total received extra credit.
