Hi Prasanth,
That depends on where do you want to work after BSc. If after completing BSc you are getting into an institute like homi bhabha, TIFR or BARC....you can do your masters and PhD there itself as its not difficult to get phd guides there otherwise it is difficult to find a good guide or you can do MSc by Research while working. post MSc jobs are lucrative too provided you score well or you can become a lecturer or asst professor after clearing NET if you like teaching or you can get into an international school with just BSc qualification too they give good salaries ,some schools may take you in without a BEd degree but you need to acquire it afterwards that you can do while working or do post MSc diplomas like radiological physics offered in BARC here..they take you in after diploma but Make sure you score well they want minimum 60% aggregate.
Either ways you can make a good career if you score well and your subject knowledge is good. Choice is yours.
Get back to us if you have any other query.
All the best.
