If you are responsible for administering the OBMEP tests at your school, you can use this application to scan and send the answer cards of students selected in the 1st. OBMEP phase instead of sending them by post. You can also fill out the RAIG and the Shipping Document.
To do this, you will need to have access to your School's account (login and password) on the OBMEP website (http://obmep.org.br).
