I don't understand you guys. ONE exercise of 3u inverse trig, and you say its too much? On the one hand you say working hard will give results, and when i DON'T work hard, you say i'm working too hard. :S
Anyway, Coroneos STILL hasn't rung me back yet. I phoned him yesterday, and on one line the answering machine picked up, and on the other I rung five times then hung up. I didn't leave a message. Perhaps I'll leave a message today.
In the meanwhile, I'll just do the 3u 1960's book i have. heheh, heaps of the topics are the same. And I can do the 4U as well, now that I have answers to mark with.
