Some browsers don’t allow this. Google Chrome does. Others might. Better still, download the Reading papers to your computer and use Adobe Acrobat Reader to complete them.  This has two big advantages over using a browser.

1) You can save your work as you go, or at the end. Then you can check over it later and if you need to, email it to someone (your teacher or tutor for instance).

2) When you print the paper your answers will also print. If you try printing from a browser, even Google Chrome, only the original question paper prints, without all your hard work.
