Graphic Design Portfolio

Hi I'm applying for 2024 entry and about to send off my ucas application.

For the portfolio, does anyone know if its a website or pdf type portfolio? The entry requirements page specifies files totalling 30mb which seem pretty small. It also says maximum 6 examples - does this mean 6 projects or something else?

Any clarification/help/examples would be great.

Guidance says "a maximum of six examples of" and then gives a list of things they look for.

Would you / did you interpret that as six slides in total, or up to six examples of each of the different assessment objectives? Hoping it will be clearer when I get onto the image portal. The written instructions are not clear at all.

FYI The info on their website says:
"In general terms however, we would expect to see a maximum of six examples of the following:
Different approaches to drawing and image making
Sketch book pages or development sheets Examples of work that demonstrate the visual communication of ideas, opinions, content and messages
At this stage in your career we would much rather see experimental and innovative developmental work rather than all finished work"

If it's six slides total, then it's going to be very crammed in and look rubbish.
