In Vedic astrology, success in a government or competitive examination (sarkari exam) is read from a small set of significators. The Sun is the karaka of government, authority and prestige; the 10th house and its lord show the career and public standing; Saturn rules service, discipline and the perseverance an exam demands; and the 6th house is the house of competition, employment and — most importantly — competitive examinations. Mercury supports the intellect and administrative aptitude, while Jupiter gives wisdom, guidance and success in learning. When these are strong and connected, the chart carries a clear examination signature.
This tool goes a step further than a general reading. You choose the exact examination and a target year, and it lays the Vimshottari Dasha running in that year over your natal signature — because timing matters as much as promise. A supportive Mahadasha–Antardasha of your exam significators lifts the possibility for that year, while a quieter period suggests steady groundwork now for a stronger window later. It also weighs the karaka of the exam type (Mars for defence and police, Mercury and Jupiter for banking and teaching, Saturn for railways, and so on), so the reading is tuned to the line you are attempting.
The exam list also carries indicative general-category age limits, reckoned as on 1 August of the exam year, so exams you have aged out of are shown greyed out — relaxations for OBC, SC, ST, PwBD and Ex-servicemen still apply, and the official notification is always final. Every statement here describes classical tendencies and timing, never a guarantee of selection, which always rests on your own preparation. For anything serious, consult a qualified astrologer who can study the full chart, the Dashamsha (D10) and current transits.
