Hello Rohit, 

There is only 60% chance of you to get B. com course through BHU UET exam 2019 with 245 marks. I suggest you to wait till the councelling as there may be slight variation in the cutoff and seats.

For more precise results you can check on college predictor,

I hope you will find my answer helpful. 

All the best.
