Jupiter and Mercury are the main responsible planets for success and failure in examination.
Jupiter is karaka for knowledge. For higher examinations, transit of Jupiter should be favorable for student to pass in the examination. Transit of Jupiter from Lagna or Moon should be in 1,2,5,9 or 11th house.
Similarly the transit of Lagna lord, 5th lord and 9th lord, if at the time of examination, is at 1,2,5,9 or 11th house from the Lagna or Moon then the student will be successful in examination. If Jupiter, 5th lord and their Navamsa lord’s transit are favorable; good marks shall be secured.
If at time of examination Lagna lord and its Navamsa lord transit is positive then candidate shall pass with very good marks. Adverse transit of Jupiter and 5th lord at time of examination causes bad result in examination.
Mercury is the governing planet of knowledge, speech and writing. 3rd and 6th house represents exams and success respectively. 12th house represents failures. So if 3rd house and mercury is connected with 6th house, one succeeds in competitive exams and if 3rd house is connected with 12th house it predicts failure.
According to best astrologer in delhi, the sub lord of the 3rd house if signifies 3, 2 and 11th house then the person will get success in competitive exams. If it signifies 9, 8 and 5th house then it is failure.
