For SM institute module is sufficient: chapter 3,4,5 are technical chapters not borring but scorring.
For info tech RTPs from 2009 or last 8 papers are must almost 60%-70% paper wo hi hota hai.
dnt study deeply bcoz headings se hi Q puchte h and in 1-2 paragraph me hi concept pakka ho jata h.
For Audit i reffered Surbhi Bansal book.only.. buy surbhi bansal book bcoz u hv holidays of diwali too, just do 1 thing, just previous attempt me jo Q Asked h un concepts pe red pen se cross kar dena, dnt study that.and remember SA names and 4chapters Vouching, verification,Company audit part 1 & miscellaneous audits. almost 50 marks in 4 chapters me h jo aap near about 2 days me biheart kar sakte ho.
and do 1 thng apne friend ko sath me rakho n study all concept verbally discussing.once u hv done this 50 marks to pakke h aur time bhi bahut kam lagega.
