Diet & exercise.: It's right to focus on your studies, but not at the expense of your health. Make sure that you still eat a healthy, portion-controlled diet and exercise regularly. The exercise will actually help your mental acuity, which will help your studies of course. And get enough sleep, too, as sleep deprivation can contribute to overweight.
