Sfm book doubt

Most of the well known books are equally good in content and presentation. Its just that the presentation suits to someone and to some not.

Just select 1-2 chapters which are critical fr u and check presentation of these chapters in well known books a the book store. In whichever book you are comfortable.. buy it and read it holistically. Gud Luck.

For ISCA, ICAI Practice Mannual and RTP(This attempt and last 3 attempts) should be read.. 

Almost 15-25 marks of question are from RTP in all attempts..
