Wooo hooo. I received the email this morning to say I passed. I have avoided the forum since submitting my assignment as I didn't want to see any posts talking about things that I might have done differently as it would have had me questioning my own methods.
Thank you Roel and Roberto and everyone one else who has given advice on these pages. I certainly learned a lot from yourselves and from doing the assignment. The question is now what to do next
It has taken exactly seven weeks from submission to getting the result.
