Accenture India — uploading semester marks details

Hello,
In my graduation 4th semester marksheet there is combined marksheet of 3rd and 4th semester.
First time i have uploaded only 4th semester marks but they rejected the task. Because marks aggregate differs from marksheet.
Then i upload both 3rd and 4th semester marks in 4th semester my task is approved but after some days again they tell me to upload 4th 6th and 8th sem marks telling that information is incorrect.
This is same for 6th and 8th semester. How to upload marks?
