Here's the mark scheme for the A2 music video production. Please note that if you started Media at Long Road in 2017 or later, then this does not apply to you, and you can safely ignore it!
For everyone else, take a moment to consider each of the different 'grade' boundaries (mark schemes don't use grades, only 'levels' as grade boundaries are only decided when the entire country has taken the Media exam).
It's vague, because it has to be vague. Technically there are many other productions that centres can decide on, both video and print. The most important levels are 'lower level 3' (let's call this a C), upper level 3 (you can think of this as a B) and level 4 (most likely an A).
What words and phrases jump out here? What do you actually have to do to get an A grade?
