personally i find complex numbers really hard but thats cos i have a shit teacher who left out half the topic and just gave us past hsc q's on them to do from the 1980s which are IMPOSSIBLE.
i dont even understand what they mean so i gave up thinking about it and started copying out the answers
not the best thing to do.
im liking conics at the moment, but then again we've only learned how to sketch an ellipse :S
