Dear Pranja,
I have a feeling that you wish to study further but at the same time you are in confusion whether you have to look for a job. Listen Pranja, as you may know, you don't get a job in very next day. But you may get it within months or year. Along with the time you look for career opportunities, why don't you prepare for MSc entrance entrance? There are career opportunities for a BSc physics holder in BARC ( for example) or other scientific institutions (please have a look at their websites). The selection procedure always start with entrance exam. If you prepare for Msc entrance, that equally well help you for such career entrance exams too.

So my suggestion is, next one year prepare for MSc exam and at the same time look in websites for opportunities, apply for it, and use your competency to get through. If you fail to clear the entrance exam for the job, join Msc.

Best wishes,
Rupesh
