Not sure about educational version options, but you can either publish your layouts to PDF or just open the layout and save as PDF.
Finally you could also print the layout using a PDF printer.
The first two option should create a PDF with exactly the size of your layout and never break it up in different pages.
Using a printer, you might need to setup the page size properly and pick 'Use Layout Margin' as margin option.
