(no subject)

Okay, there are 5 parts on tomorrow's exam:

1. Entity-Relationship Diagram - should be a breeze.
2. Query languages - should be okay, except if there's much on insert/update/create
3. Functional dependencies and normal forms - probably okay, unless she asks about 4NF/5NF
4. Query optimisation - okay, if I don't forget what I'm talking about.
5. Transactions - a breeze, unless she asks for recovery

I can pass this exam for sure. I should do okay. Why am I panicked?
