Hi,
I see that you have done BCA in Data Science Analytics but you are confused between either to go for a job or pursue further studies.
So, in my opinion you should go for a job and side by side also study further, because at this stage there will be difficulty in finding some good paid job as a fresher.
Now when you would be studying further you would have become specialised in that field and with that you would also have gained some work experience due to which, now you will be able to get a better job.
Hope it helps :)
