I found this website very useful for all the competitive exams specially for SSC and railways. Faculties here all good, knowledgeable and responsible. They all teach very nicely and very briefly. Here you get paid as well as unpaid sessions so it is not mandatory to pay a in order to get any kind of knowledge. It is good for those too who could not spend money in competitive classes. They have live batches too so that you will be in touch with the teachers for better understanding of the subjects. Classes for maths, aptitude, reasoning, general science, general knowledge, current affairs, Hindi, English and other competitive subjects are available. I love to study from there YouTube channel and this is the best.
