Retrograde and combust Mercury, retrograde Jupiter & Ketu afflicted moon are not good for intelligence/grasping abilities.
You have been unders Mars mahadasha from 16/7/2011 and while Mars is yogakaraka for your ascendant, but its placed in 6th house in Chalit thereby not giving success and stability. You are under peak SadeSaati since Aug 2015 and Saturn transiting your 10th house in October 2017 will give you a new launch (with tremendous hardwork). Better opportunities will come once Saturn reaches 10th house in October 2017.
You will start Rahu Mahadasha from 16/7/2018 for 18 years and Rahu is very strongly placed in 4th house (with combination for professional success in nakshatra and sublord).
