Syllabus Changes

I was initially planning on giving my exam at the end of this month but i will be travelling for work for 1 week,maybe even 2. I can’t give my exams before I travel because I definitely won’t finish my revision before then but i’ll try and study while travelling and plan on giving it as soon as I’m back. Unfortunately I won’t be back in town and free till the 4th of September. If i give the CBE exam then, will the new syllabus changes be in effect? should I be studying those 2 extra chapters as well?
