ECOS Registration and Payment

I did not find the option to attach the invitation letter in the system. What should I do?

There is no such an option. You must combine your student ID with the invitation letter and attach it as single file in the system. If you are underage, you also need to add a letter signed by your legal tutor (parents, etc.) allowing you to attend the school.

I submitted the wrong file during my registration. What should I do?

Please, remove your registration and register again.

I registered, but my registration is still been processed. What should I do?

As processing the registration is a manual process, it can take some days to be concluded. If it has been more than 5 business days, please write to us.

I already paid, but the ECOS system does not state it so. What should I do?

The system can take a few business days to update, especially when paying by "Boleto Bancário". If it has been more than 5 business days, please write to us.

If your payment method is "Boleto Bancário", be sure to take in account if the payment is not scheduled instead of already done.

My University will make the payment of my registration. What should I do?

In this case, please contact us as soon as possible.

In this case, please write to us, so we can help.

Registration Fee Exemption

I'm exempt to pay the registration fee?

Only ICPC World Finalist going to Egypt in 2023, Brazilian "Maratona de Programação" Medalists of the last Brazilian Final (Gramado, 2022) and female students are exempt.

Students that do not fall in the previous categories are not fee exempt even if they are OBI/IOI medalists, ICPC World Finalist and Brazilian Medalists from other years.

How do I know that you know that I'm exempt?

When you are selected to the school, you receive an invitation letter. This letter will state if you are exempt or not.

I should be exempt, but the letter says that I must pay the registration fee. What should I do?

In this case, write to us explaining why you are exempt, so we can clarify the problem.

How can I register as exempt in the ECOS system?

You can't... Register and select the payment method as "Boleto Bancário". We will manually register you as exempt.

I'm exempt, but my payment appears as Processing/Pendente or Canceled/Cancelado. What this means?

It means that either we did not change the status of your payment yet (it is processing) or that we already canceled the payment as you are exempt (it is canceled).
