The Rahu Mahadasha and the antardasha is not a good period. This is the last antardasga of Rahu and will be till July 2017. This is indeed little better for relationship as there is an exchange on your 5th and 7th house. Saturn which is the 7th lord is in the 5th house and 5th lord Mars in Saturn. This exchange is good for taking your relationship forward, however not much beneficial for exams. To prove your self in the class, you should be working hard.
