Mumbai University — Filled incorrect information

Address:

Mumbai City, Maharashtra

While filling information on the mu website, instead of the serial number of the statement of marks of ssc, i have accidentally filled the serial number on my ssc passing certificate. Since i have already applied for some colleges, i am not able to make any changes. I want to know if this can cause any major problems in my admission process, and if so, i'd like to know if there's any way to fix this. Please reply.
