an android app . all the users should be connected to one the server.

the app i need is basically of a type where user is getting a series of question sets with each question having four options to choose a answer from. after completing one question set user should get the result of his performance and the server should know about it and keep an account of it. it is similar like online exam but here are number of exams and it is not necessarily that user should be always connected to server only his results should be send to the server and it should keep an acc of it. i will provide you the question sets.
