"Circle of Answers" is an application that will help you in difficult times. Answers to the questions you raise. Just ask a question and shake the device, and you will immediately be given the answer to your question. For example, ask a question - "I'm looking for tomorrow's exam?" (The answer to this question in 2nd screenshot).
And most importantly - have fun.
