Hello Utkarsh,
IIT-JEE preparation is irrelevant of which coaching classes you attend. At the end, your efforts matter the most. There can be no comparison between coaching classes, all of them help you improve your score. You have to solve practice questions as many as you can, learn more and more concetps and keep revising the topics you find difficult. Again, it is not difficult to crack IIT-JEE, it just requires planned efforts. All the best for your preparation.

You will surely be able to get a seat in colleges of Delhi if branch is not a major issue for you because seats in Delhi are mostly reserved so you can't expect much.
