Hi ujjwal
J.K thukral is the best book for b.com (H) 2nd year. Just you need to go through the complete book .
or you may study only example questions in book.
It is sufficient for you even i also study from the same book and i got 58 out of 75 marks.
I personally suggest you thukrak because so many questions in the exam just copy and paste from the example section of J.K thukral even it is a best book for self study also.
the explaination in this book is quiet impressive.
So dont worry and keep maintain trust on thukral
Thanks and Regards
