SBL Latest Technical Articles – The real Essence?

I’m not sure what you mean by ‘real essence’.

I think the ones you referred to were all written by a member of the examining team. Their purpose is to provide information about certain syllabus areas. Perhaps the areas are new and the articles give help as to the depth of knowledge required. Perhaps the examing team think the topics have been poorly answered in the past.

It is not reliable to assume that a recent technical article gives information about questions in the next exam. However, particularly with new syllabus content, the examiner might feel it wise to produce an article before a question is set at some point in the future.
