Writing spells in a spell book question

[I Hate Nickelback]

Can you write a higher level spell then you can actually cast in your spellbook? I know you couldn't cast it, but could you have it in there?

Yes, if you pay for it. The free spells obtained at gaining a level is more restricted.

Ok, thanks. That's what I thought.
