Given these constraints, it would be close to impossible for any one person to succeed in isolation. Second, professional science is a collaborative exercise. Scientists routinely design experiments, analyze data, and write papers in groups. In his acceptance speech for the Nobel Prize for the structure of DNA, Francis Crick commented that the reason he and Watson had arrived at the solution, and Rosalind Franklin had not, is that he and Watson were each other's constant critic, challenging the other's ideas and thinking, while she was working alone. For students and for professionals, working collaboratively presents special challenges.
Some collaborations work very well and are maintained for years or decades.
Others last for the duration of a single project, and still others are not productive at all. Talk with your group about this. Chances are that each of you will have experiences from prior courses. One quarter of your grade will be based upon your individual performance on this final, which is built directly on the work you have done in your group lab reports. This is a final for which you quite literally prepare all term, and students who have conscientiously contributed to their group's understanding and analysis of the data over the term always excel in this exam and students who do not, do not.
