The period of Rahu that is going on will be challenging, you should be more focused and willing to put efforts. I have given you the strong beej mantra of Rahu. Also your lagan is weak , wear any of the stones. Strengthening the lagan will build your confidence , help you be more focused and accept challenges. I do believe that doing these simple home remedies you will pass your exams.
