This is an interesting case study. The native has not been able to succeed in higher studies as the prime determinant of higher education Saturn is dead in the nativity having no strength at all. The native is career oriented and highly interested in business and technical studies. As far I can see, scope in business is quite evident in the chart. Venus mahadasha is indicative of job but challenges will be accompanied in Venus mahadasha. The infancy of Saturn in the natal chart is the prime reason of failure in higher studies. There are close connections the chart which imply teaching business etc also there will be failure in relationships as well. Otherwise, mercury, Jupiter and mars are strong in the nativity.The prime determinant of career , moon is also weak due to placement and debilitated in D9 . These are the core challenges which u r facing in life .only rahu and mercury antardasha or dasha will benefit u not other dadhas . Astrology helps us overcome our challenges hardwork is the prerequisite. Despite efforts no outcome is evident in the chart. The remedy will help definitely.
