You can try to use the image IOI 2012 organizers is providing you on their website and see what units are available. As some units might be forbidden even if they're available for security reasons, I suppose that the safest way is to ask the organizers directly at IOI practice session. In the end, that's what it is for.

AVL_Tree? Is there any STL for it in Pascal?

By default, you can use any library in standard pack of your compiler. Eception is those, which forbidden for security reasons, such as working with net.

I've discussed this with the developers of CMS (the testing system that will be used on IOI). You can use Math. Other modules are not guaranteed to work (for example, using Delay() from SysUtils will raise a sandbox error). AVL_Tree is not a part of FreePascal, it is a part of Free Component Library (which is part of Lazarus), so I'm pretty sure that it is not allowed either.

There's an environment pretty similar to the one that will be used during IOI available at http://c.popoffka.ru, you can log in with CodeForces:cf and see if programs using AVL_Tree will work.
