Punjab

The answer depends on the region where you are searching for the coaching. Let's see the scenarios of some of the major cities:
1. Chandigarh is the coaching hub from the past decade. The best coaching in Chandigarh would be Lakshya Institute since they managed to produce AIR 1 in JEE 2017. Allen Institute also gave top ranks in JEE 2016 and prior years as well.
2. In Ludhiana, institute named Edusquare has got everybody's attention and has given even better results than Aakash, and it's growth is exceptional. They have a selection criteria because they have a very limited seats.
3. In Jalandhar, no institute has done things better than Knowledge Campus. They've been consistently giving results and the faculties are very well experienced. The assignments and the tests conducted are top notch.
4. In Patiala as well, Lakshya Institute has had the monopoly of producing results.
5. In Amritsar, you will have to join Aakash institute or Veron Institute as these two are the most successful ones in this region.
