Hello Sakshi!

Mock round is a kind of test round and not the actual seat allotment results. So you cannot completely rely on mock result. Because, students change their choices in accordance to the mock result. Until round 1 results are out, it cannot be said for sure whether you will get a seat or not. Even if you don't get alloted in your preferred institution in round 1, you might have chances in subsequent rounds as well. So don't lose hope.

All the best!
