Wow - what an interesting chart. I'll have to mull this one over, but in terms of studying, I'm thinking Mercury, Jupiter, 9th house sign and ruler. Mercury's in the 2nd, so that suggests to me that you need concrete results from your intellectual efforts, you're not a theorist, you're a pragmatist and perhaps the subject you choose to study should not be something too "airy-fairy", but which has a practical application in the real world. Mercury is the ruler of the 9th house sign, which is Virgo. Virgo here again suggests something practical, vocational, maybe something to do with nutrition or health in some way. Finally, Jupiter is in the 7th in Cancer which says (to be very brief) relationships and nurturing to me, so now I'm really thinking perhaps nursing might be the way to go? Transiting Saturn is right on your 10th house cusp, which hints that perhaps now is the time to buckle down to studying because you've got the right mental attitude to your future career (responsible, sensible, prepared for hard work). Hope that helps!
