Wabs Talk (Moti Nagar) keeps less students in a class around 10-12 and faculties are also awesome, specially Reuben sir! When I joined the classes I was in little hesitation but their way of teaching is really unique and you will find it simple and easy to learn and understand. Grammar and speaking sessions on everyday basis will definitely boost your confidence and there are so many public speaking competitions which will give you a huge platform to speak in front of others. And believe me, learning something new will become a part of your daily routine.
