@pinanay you’re better of asking an explanation from the assessing authority rather than comparing syllabus from previous applicants. That way, you can argue your case better as you cannot reason to them based on the results of previous applicants. They would most likely reply by saying each case is different.
I’ve only used IPA once for a client as that was her preferred authority and never again would I want to deal with them. Also had an issue with them which I questioned as I didn’t agree with how they dealt with my client’s case. I stood my ground and they stood theirs. In the end, I demanded for a refund for my client as I found a loop hole. They granted a refund in the end. Went to CPAA instead and the issues we had with IPA didn’t become an issue with CPAA. Also, customer service was so much better. I stayed using them since then.
