Hello Mohsin,
I have not clearly understood your query. What is BCA without graduation? You can definitely seek admission to BCA based on your 12th marks even if you have passed in 2014.

You need to score a minimum of 50% in HSC to pursue BCA.

You can seek admission in BCA but your choice of Universities or Colleges is restricted. You may evaluate doing BCA from Symbiosis University, IGNOU, etc which accepts non Maths students in BBA.
