Dear Student,

Yes, you can fill any application form from any device but you need to know the the smaller the screen sizes the more problem you will face. Like when you are filling your application form there are some lines maybe not visible or collapsed due to smaller screen so you can't read the full instruction and can do mistakes in any part, yes you can use desktop mode also n smartphone but that function also fails some time. And also when you switch to any other tab for a moment then you need to complete the each and every process again, so it will take time to uploading the documents.

So better if you choose big screen like Tablet or Laptop or any desktop for form filling so that you can manage everything easily and upload every document in proper manner.

Good Luck :)
