I want to ask if there is any option to alter the choices filled by us at the time of locking?
Or is there any option of internal sliding after taking admission in dtu, in which we would be allowed to fill FRESH choices?

Actually I filled Mathematics and Computing above IT and Software in DTU preference list, and I am so pissed off, that why and how I did this blunder, please help me out now..

I havnt filled NSIT form, I have currently taken admission in NIT kurukshetra CSE, now where to go finally?
