Hi Deepti,

Both Aakash and Resonance are regarded as top-tier coaching centres when it comes to NEET. More than the coaching institute, it is important how hard the aspirant works to be successful. Both the institutes have proved themselves time and again and have had many students coming out with flying colours. Therefore, choose anyone and work reasonably hard on the guidance provided by them and you are sure to succeed.

However, you might want to choose between the two based on other constraints such as distance from home, convenience in travel, etc.

Hope this helps.
