Students would have done very well in the last one year by scoring excellent marks. Now you will start having more obstacles on your studies. Guru bhagavan on your 12th house, would affect your good mindset to concentrate on your studies. If you are a teenager, then your mind would get occupied with seeking for boy / girlfriend.
You need to work so hard to get good marks, especially if you are doing 10th and 12th grade. The good news is you are having excellent time from Mid Jan 2016 for about 5 months. So you would be able to catch up and do well on your exams towards the end. You will be lacking on your energy levels, hence sports person needs to depend on kundali and favorable maha dasa.
