Could you analyze my birth chart and explain why I am getting a lack of concentration in my education

The existing deficiency of focus and mental block in taking CAT preparation in the case of Rohit Sharma is majorly associated with the state of the Moon (mind and emotions) and Mercury (intellect and learning). When the Moon is afflicted by such malefics as Saturn, Rahu, or Ketu, it may result in the emotional instability, restlessness, and inability to remember the information. Likewise, when the planet Mercury, which controls the intellectual power, is weak, inflamed or occupied by malefics, it may cause a deficiency in the power of the intellect, concentration, and memory. Also, when Rahu or Ketu is affecting the 3rd house (effort, communication) or the 5th house (intelligence, concentration), that may become distracting or a mental mix up. The existing planetary Dasha or transit could also be an inauspicious one particularly in case Saturn or Rahu is underway with delays and hindrances in concentration of mind. The fact that these astrological factors occur shows that the mental block is not permanent and exists due to planetary timing and not ability. This stage has to be overcome by patiently biding time and following routines of studying during times that are more stable as shown by positive transits particularly during the Mercury or Jupiter periods. In total, the chart of Rohit indicates that his innate focus and acquisition capacity will come back to him assuming he is aware of these cycles, which will enable him to pass the exam.
