A lot of hard work has to be done to prepare for a government job and you cannot pass the exam without the right study material. I bought the books of Arihant Publication for preparation and I did not benefit from them at all. The pattern of the exam has changed and Arihant’s books are on the same old syllabus. Details of topics are very useful in books and nothing comes from their books in examinations. I have wasted my money on Arihant’s books and I would like to give the same opinion to the people that they should prepare from any good YouTube channel, not from their book.
