I can give you a full evaluation of your horoscope which will convince you where you stand a chance to be holding a doctorate. It is a few hours work and you will have to come through Paid Consultation after reading my blog navagrahastro.blogspot.in and get an overview of how such calculations can be done using astrological mathematics.
Normally I would not dissuade anybody from learning more, but here is a case where your birth details do not at all give any encouragement in going for such high powered education. I will be the happiest man if you can override my evaluations and get a doctorate.
