P.c tulsian for costing, fm? can i pass using this book

Hello friends and seniors :) :)  . I'm an IPCC student who beleives in self study. My query to all of you is whether can I pass using P.C.Tulsian's Costing and F.M books. I am really fond of that book as I can understand everything well in that book . But I'm confused whether I'll be able to clear the exams using this book. It would be of great help if seniors and friends advice me as to what I'm dong is the right thing. Are there people who have studied just Tulsian's books and passed CA IPCC?? I really like this book and when I see Paduka's costing book I feel its not for self study and also I don't get confidence in the subject. Please help. Thank you in advance :)  :)  I wish everyone All the very best for your preparations :)  :)
