More overheads just add to your presentation time, but don't be afraid to add more if it's necessary. Include the question and answer on an overhead along with any supporting information. Use drawings when possible. Your answer should always include a graph that exhibits trends in the data . Delegate each part of the presentation to a group member.
Someone can make the overheads, the others can present each part of the discussion.

By performing better on Exam 2. Students who perform better on the second exam will have that exam count for double, and the score from Exam 1 will be dropped. This is an extreme case, but often happens.
