Lee I did my Diploma via supported distance learning which was lacking in the 'supported' element so had to do a fair bit od self directed research for this unit. The process I followed was to download the assignment brief from the NEBOSH website and structure my report based on the headings covered in section 2. I did eventually get offered a revision session from provider which I thought was a day but turned out to be a 30min slot in the day. The day wasnt wasted as I had prepared a draft report based on the above guidance and the assessor said it was a very good start and recomended a couple of revisions. End result was a 68% pass which I was well pleased with but more down following the NEBOSH guidance than anything else, the examiners reports were also very useful. Good luck it's worth it when its all over and you get the final diploma Kevin
