CBE exam techniques

I gave my F9 CBE last sitting (June 17). I had come across a YouTube video from Acca Global where an investment appraisal question was answered in the CBE response sheet. This helped tons in terms of CBE exam etiquette and how the workings had to be made and linking the working to your main table. I cannot seem to find any such video for F6 for section C.

If you are aware of such a video could you please post a link to it?

P.S: Cannot seem to find the F9 video but I am sure I watched a video from acca global’s youtube account this August. Not sure if they removed the video.
