Hey, it all needs to be in one PDF. What I did was took all the documents I needed for one section (like the finance bit) and uploaded them to ilovepdf and ‘merge pdf’ and this puts all your files into one. You can then upload this into the section.

If that pdf is too big you can go back to ilovepdf and ‘compress’.

I did this for all three sections. Got approved in a London a few days ago ☺️

Hope this helps!
