Rajkumar book for idt

Havent heard but I found the Rafi books affordable and very explanatory but being a last minut estudent i preferred padhuka as it was organized and summarized and theory subjects need more summarization than explanations. 

My personal preference was Padhuka was IDT and DT. In PCC, I used padhuka for all subjects but in final only for the taxes. 

this book is available at cabooks online. 2 modules viz. excise and customs is available there along with question bank. first2 modules mrp is 400 and 300 respectively. check there
