The Combined Defence Services Exam offers both male and female graduate candidates to join Armed Forces for both Short Service Commission and Permanent Commmission. The CDSE is conducted twice a year by ‘UPSC’ in three phases- (1) Written (2) SSB Interview and (3) Medicals.The written exam focuses on testing a candidate’s knowledge of English, Maths and GK. Keeping this in mind we provide our students with GS classes relevant to contemporary time so that they are well equipped with the current affairs which in turn will benefit them in SSB as well. For English we emphasize on grammar, vocabulary, reading and writing and speaking skills of the students. Written and Spoken English play a crucial role in SSB further on. For Maths, students are encouraged under the able guidance of our teachers to practice vigorously. Our teachers are proficient and well aware about the latest pattern of the exam and thus guide the students in the appropriate manner. A student appearing for Combinned Defense Services Examination (CDSE) can target four sectors with this paper: IMA, OTA, AFA and INA. With the exception of OTA all the other three require Maths as a subject, while OTA focuses only on English and GS. Col. Roy Defence Academy is the best Coaching Institute for CDS preparation. Teachers work on psychology of teen age children and their behaviour pattern.
