It's quite a while ago that I was in this boat but what I did was:
Went to FTS at FAGC and bought their notes on Air Law and Procedures.
Went to Avex at FALA and bought their notes on Air Law and Procedures.
Went back to the country in which I was living at the time and studied for weeks and learnt the questions and answers off pat.
Went back to Avex Air and did a four hour one on two quiz and counter quiz with their then CFI.
Aced the exam.
Did I overkill? Yes, most certainly. 96% means that you've spent too much time exam learning but the CAA had given me only one shot at the exam as of my exemption package on having to write all the ATPL subjects again. I'd let my IR lapse by about 7 years so had applied for and been granted an exemption on having to rewrite all the subjects, provided I passed Air Maw and Procedures in one attempt.
There were some extremely sneaky questions in the exam and some were designed such that, had you answered the first one incorrectly, you would have set your own foundation for answering further questions incorrectly.
I don't know whether Babcock are still in business at FAGC but they used to have notes and of course, there are training organisations away from the great stink.
Good luck.
