I have already studied Auditing Subject when i was appearing for paper T8 Implementing Audit Procedures back in december 2006...so i want to share something important here...
Dear Brother I joined 2.6 Tution for paper 8 it is my personal experiance that Auditing subject is absolutly nightmare for lot of students because when i was studying paper 8 there are nearly 15 students in class of which only 2 students were appearing for first attempt of audit otherwise lot of them were repeaters and every one attempting his 2nd even 3rd and fourth attempts....Audit is the most difficult paper of whole part 2 i have personal experiance of it and if you were CAT student you will probably know about the passing rate of paper 8 and only very few people used to attempt and nearly 25 to 30 % were suceed same is in the case of paper 2.6...
My advice to you is to properly study 2.6 with very very good teacher otherwise it'sd very difficult to pass i don't know about your city but in karachi there is only one best teacher for Audit is SIR JAWED ZUBAIREE is also studied from him he is "ZAKIR NAIK" of Auditing and lot of people are well aware about his prestige...
FTC is much much better than BPP in all subjects because the written style of FTC is far much professional than BPP...and one drawback of BPP is that it contains extensive details of excluded topics... and senior most teachers always refer FTC to students because BPPs standards are nothing compare to FTC
You can but as you mentioned me that you are curently taking 1.3,2.2 and 2.1......dear brother it will be a nightmare to attempt next time Audit,Taxation,Financial Reporting Togather because Audit and Financial Reporting is vast course altough 2.3 is little course but difficult one too....my advise to you is that nest time you should start taxation along with Financial Reporting and leave audit at least for next attempt...
