<p>You could try borrowing them from your local library</p>
<p>That's what I did, I just put the books on hold then went and got them when they came in</p>
<p>If you need to keep it for longer you can copy some questions down, photocopy some pages, return it then borrow it again the same visit, renew it, etc etc</p>
<p>finish the blue book. if you've just ordered it then you won't need other books for some time. once you're done with that buy or borrow the old ones.</p>
