You have to state whether you have applied for re-evaluation or not in the examination details 'result status' section. If you haven't then fill in the results, upload the self attested marksheet and academic details and proceed. If you have applied for re-evaluation then in the same section you can click on 'applied for re-evaluation' and fill the academic details as you've got with the marksheet, uploaded. You can then either wait for your re-evaluated result before the last date and then make the payment after updating your documents. Or you can simply apply with what you have got. Academic details section can be edited after the payment also so you can update it when you get your re-evaluated result. However, you cannot edit the uploaded marksheet after payment but its not a problem. You just have to keep the updated original marksheet with you at the time of admission at whichever college you go for.
