Mere paas surbhi bansal mam ki May 2015 wali auditing ki book hai.. kya mujhe naaye book le ki zarurat hai? kaun si book achi hai sumit aggarwal ya vikas oswal?
Surbhi Bansal is good book to understand the topics. However, It doesn't help students help in answering in exams. In this case, I would suggest you to complete the surbhi bansal in very short span of time [for only those selected chapters which required conceptual clarity] and refer the practice manual and RTP provided by the ICAI. This would help you to understand the type of question asked and how to answer the same as per ICAI.
