Hey Manisha!
Firstly, congratulations on scoring such amazing marks!
You do have a high chance in the second list and to get into the college.
Just have patience, and wait for the list to come out.
Don't worry if you don't get selected. Just remember that a college plays a very little role in our life. All that matters is your hard work, no matter which college you go to.
So focus on the main part. I hope you have applied to other best colleges in Kolkata.
Hoping to see you in St. Xavier's College soon.
Wishing you good luck!
Just don't lose hope.
