Hello neha
You have to try hard as dasa running In sun and Saturn.till nov 2017. Once Saturn moves to natal 5th house and aspect labha house ..you sun is quite good. In dasama it has become weak..thats why you are getting dishearted.
I think you planning for exams is lacking…you will sure get govt job
Time period will be you stress as you running Saturn sub period..so its best to work hard during this period…situation will improve once Saturn moves to dhanus raasi. From feb 2017.
No need to worry. In dasamsa sun conjunct Jupiter the 10th lord ..so try hard plan well.
