Singhania income tax book

Hi , As per  my Knowledge, you can refer to Student Guide to Income tax problems and Solution by same Author, if you are solving problems and not able to solve (Tough) problems  . Else If you wanna pass exam by reading Service tax & Vat, you can read Module. if you are not able to understand Theory as  well, refer Girish Ahuja book , for simple English. Please bear in mind that Theory alone carries upto 40+ marks in Tax.  This is my personal opinion, no reference to others.
