I'd do both. Its not always giving someone your undivided attention that makes the difference, its just being there. You could sit by the bed and study while she reads the paper(after the initial chat, anyway). Or work out a way that she can help you study with question cards or mock tests. At the end of the day, revision a few days before the exam should be going over stuff you already know to recap. There is very little you can learn in a short space of time. Thats just what I'd do, anyway. GL with your exam!
