Hello Lareb Khan. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

And yes, your paper will be accepted by VIT!!!

Actually, it is not necessary to click the "Submit" button because it automatically sinbmits your paper. Only if you want to submit the paper before the end time, should you do so.

Hope this helps you and all the best!
