I am a B.sc. graduate (chemistry) from Goa . I have a keen interest in civil services like the Indian police services and the central police forces. sir, am trying my best to join one of these. but sir, Goa being a small state ,there is no sufficient study material ,and also there is no much exposure to such competitive exams. Sir, I have already applied for the Asst. Commandant exam of the CPF. Sir, please guide me as how I should prepare my self for the exams. I may also be interested in the previous years papers?

Any leading book publisher in your area should be having the relevant books and study material required for preparing for the Civil Services. Further, it is the main text books of your Optional that are the most important for studying for the optional. If you still find it difficult to have adequate study material, try the option of enrolling for coaching through correspondence from some reputed Coaching Centers such as "Brilliants". However, do keep in mind that there is no substitute for a planned, systemic preparation spanning 1-2 years for this prestigious exam. Also keep on applying for other exams such as PO exam conducted by various banks and RBI etc. so as to have a good practice and feel of the competitive exams.
