These textbooks have been especially created keeping the students' enduring desire for improvement in their subject matter. With the recurrently changing pattern and difficulty-levels of various competitive exams, TathaGat feels that there is a constant need for updation in the way the students prepare for these examinations. Combine these factors with the ever-increasing competition and these books become the need of the hour for every aspirant who wants to ace these tests.
TathaGat has a long pedigree of experienced mentors who repeatedly monitor and analyse these examinations and try to calibrate the students' preparation levels so that every student is on a par with the current standards of the exams. And, consequently, the creators of these textbooks, who themselves have had a long stint in teaching, have handpicked the concepts and painstakingly provided detailed explanatory chapters paying special attention towards making the concepts easy to grasp for students of every strata in terms of capabilities. These textbooks will be particularly beneficial for students who may not have access to classroom programs for their preparation as the concepts and questions are exhaustive and at the same time interesting in nature. For those that have taken classroom training, these textbooks will serve as a sine qua non for adding that extra edge that champions need.
