Taking a level art without doing gcse

Our school limits the amount of gcse subjects we can take quite drastically, (only two options, the third is always a language and suggested to be whichever you’ve studied from year seven). I initially chose art but switched to drama because I didn’t want to lose enjoyment for it. I’d like to take it for a level and have applied to take it at the school I’ve been accepted to, but I need to present a portfolio. I’m not sure what to include in a portfolio for it to be truthful. What could I include or what should I work on to develop my art skills so they accept it. (I’m now considering an arts/architecture career and need to take art). Thank you!!

does the school offer any guidance on what to include? if not here's an example of A level art portfolio criteria, but i would think if they're asking for a portfolio they'd give you some idea of what they want to see/how many pieces. In general, I would say try and show off as many different skills, media, subjects etc as you can. some ideas for things to include:

and try and do these using different media, e.g., a watercolour landscape, graphite drapery study, charcoal study of a wooden table, ink sketch of a person you see on the street, etc. good youtube channels for tutorials if you need them is Proko for a wide variety of subjects/media, and Stephen Travers Art for specific tutorials on pen drawing and drawing buildings.
disclaimer: I did my A-levels several years ago so my advice may be outdated, i also did Fine Art specifically so this may not be good advice for other art a levels
