a level geography terminology in exam

are we still allowed to use 'LIC, HIC, NEE' to denote countries? i looked on mark schemes (edexcel) and they use something called VHHD which im not sure what it is, if it's preferred or if you will get marked down for still using the abbreviations from gcse?

In longer answers especially, it's probably best to write it out fully and abbreviate in brackets, then throughout the rest of your essay use the abbreviated term

would you do that with long acronyms? writing out OPEC (Organisation of the Petroleum Exporting Countries) in like a 6 marker would feel like a waste of time but tbf my hand gets cramped so easily
