BCom(A & F) course is from IGNOU university whereas the link which u hav posted http://184.108.40.206/14837faq_bharathiar_icai.pdf is of bharathiar uiversity. One can do BCom from any of the two universities.
But in case of IGNOU, we can get the BCom degree within 1 year if you have cleared IPCC.
"For the students who have already completed the Chartered Accountancy First Stage (lntermediate/PE-II/PCC), the minimum period of study shall be proportionately reduced. Thus, such students can complete this programme within a minimum period of one year (with the condition that the total period including one year at IGNOU should not be less than three years from the date of passing CPT) and a maximum period of 4 years."
This is written in the latest prospectus for this course for 2013.
whereas, in Bharathiar university,there is no such advantage. It will take 3 years to get the BCom degree!!
I am also going to enroll for this BCom from IGNOU.I have cleared my IPCC.
