Back to school

I probably should've used this title yesterday, but anyway.

Reminders:
1)Chemistry homework all due by Friday. Then there's this mindmap we're supposed to do on Chapter 2 that's due on Friday too.
2)Physics, draw the diagrams. You know, the alternating current diagrams. The one with 4 diodes.
3)Maths holiday 'homwok', due tomorrow. In foolscap.
