Okay, in the light of events provided by you, the time of birth appears to be correct i.e. 2.10 AM. now coming to your querries, my response is appended in between:
Dear Gurujan, pls, advise me if it is worth putting effort to get mba and how beneficial will it be to have a career in finance related job.
The mutual aspect of Saturn and Venus (placed in angles) and placement of 10th lord Moon in 11th house does indicate favorable results in Business Management and Finance related job/profession.
Will I be successful in my current sade sati.
Yes, there are some good chances. The problem, due to which, you could not make up earlier, appears to be operation of antardasa of Combust Mars (August 2006 to Feb 2007) followed by antardasa of Cruel Rahu (March 2007 to August 2008). Therefore, from the onstart of Jupiter's antardasa from Sept 2008 onwards, you can have some average results. While, the significant positive results in respect of professional matters are more likely to take place during Moon/Saturn (January 2010 to July 2011)
