Hi Souvik,

Hope you are doing well, here is the answer to your question of how to get admission in BCom before you get your 12th result. 

B.Com is a UG Course of three years, for the admission to B.Com you need to have 50 -60% of marks in 10+2. It is the eligibility criteria and you can directly get the admission into many of the colleges. While some colleges even keep entrance exams. Any admission if you want to take you can do only after the 12th result. It is purely based on your merit. I hope  I have cleared your query. Any other queries are always welcome.

I think it helps you!!!

Keep Smiling:)

*Chase your dream goal*

Wish you good luck!:)
