For 1st group i think actually our senior's advice that audit is the tormentor,I think it is totally incorrect, the real evil is PAPER 1 accounts is the real evil. Yes audit is a universe but accounts has all the ingredients of being a killer. Prepare thorough and still u hv a question jo sab pe pani fer deta hai,example is this time 's holding company question,pata nhi kaha se aya tha. MAFA is quite easy but tricky. Law have direct questions,so doing munish bhandari's book is enough.
Second group., as the legend is DT will kill u big time,so vast so technical u dont get tym to think even a bit about anything else. This time's Dt was straight out of the mind of a devil,who i dont think would be able to solve it fully in 3 hours.Costing is COSTING,dont mess with it, ISCA ratta lagao khushiya pao(mug it up n have fun), IDT is the saviour of group 2. ALL IN ALL,the biggest mistake i did was i understood all the syllabus topics but i didnt crammed it which I think was a sort of handicap in writing the questions in exams.
P.S dont miss e filing aspect of everything be it MCA,TDS return,IT return,tax payment,any complaint filing,etc. In short anything and everythingrelated to web connect and dont waste ur time learning sections. Insti gave all the section with a brief hint of what they are about,concentrate on meat of the section,not its nomenclature. PEACE
