Yes Doos explained it very well. Almost every section of the Gem-A diploma is discussed till it's dead in these chats. Doos and Annie and I (Along with many others) Spent my entire three and a half year FGA distance learning course thrashing the whole thing out every week.

I was such a lucky student to have two such dedicated teachers. Many other forum members also became qualified gemmo's with help From them.
