Hi Sahil

I don't think that you will be able to make changes in the application form after fee payment. However, give it a try by logging in. If there is any major change in the application form then you write a letter to DTE, Maharashtra stating your concern. I would suggest you to get the changes done as soon as possible.

Here's the link :

Hope this helps. If not, write back.
