TISS is one of the institutions that releases their lists far earlier than other universities such as DU or JNU, the probabilities of selected persons transferring to other colleges once their lists are announced are quite significant.

So, if your waiting list number isn't too bad (between 1–10), there's a chance something will work out.

But don't forget about your other possibilities. Don't rely solely on TISS. You must always keep other options open for you.
