did you got any subject with 60+??? for example if u got 66 in tax and 59 in law.. 59+66/2= more than 60%... so u will get exemption in law..... I guess you got 60+ in some other subjects. so u got exemption
I think only two exemptions will be allowed for group-1 out of four papers though you have got 3 exemptions, for group-2 only-1 out of 3 papers as per ICAI. Please confirm for ICSI.
