Do you have ToB installed? If you do... get ready to abuse one of the game's greatest loopholes!
Scroll Scribing.
Now, now, before you think I am whacked, realise that ToB enables you to erase spells. So what does that mean? Why... if you want to scribe a scroll, but you already know it, erase it first, then voila! Instant ability to scribe that spell again!
"But scrolls are so expensive... ..."
There, there, this is where we make use of the five-fingered discount that all Bards are blessed with.

So go forth and steal! Steal and scribe till you choke on the cheesiness of it all! Join the smelly ranks of the Society of the Parmesans!

If you do not have ToB installed, you can still rely on scroll scribing to gain XP to a certain extent. Tradesmeet and the subquests in Umar Hills are very easy to do as well.
