Dragon and rat are compatible. You won't have trouble in your exams if you perform as normal. You shouldn't engage in the entertainment too much. Otherwise, your study will be affected.

For your health, you should pay attention to respiratory problems. You'd better stay away from the smoking areas.

Honestly, you are not lucky in your money matters. So you should avoid speculations or any other risky investment.
