I need to print a5 page into the middle of a4 paper

I have a pdf document from a school subject which I need to print out and write some extra notes in during the lesson. My plan is to print it in a size close to a5 in the middle of a4 page, so I can make notes around it, but I cant figure out how to do it... I dont care if I export it into images/word or whatever, I just need an easy solution which wont take time to resize each individual page or sth like that.... thank you for your help(in short, I need to print a5 into the middle of an a4 paper)
