Hi Andrew, I've saved some constants to my calculator memory. I find the screen font way to small for my eyes these days. Have been using my daughters NSpire. Has Backlit display, just the ticket but she's re=-claimed it for school! How dare she!

I saw guys using Perl, looked excellent...hmmm can we teach an old dog new tricks?
So far so good on the course. It's been more testing than I expected and definitely taken more time than expected. The maths content is ok but there is a lot of manipulations, easy to make an error.
The homework is quite testing, halfway thru week 10B atm.
I'd recommend this course but I'd also recommend that people undertaking the course be reasonably confident with maths and physics principles to year 11/12.
Unfortunately there have been a few students just hanging on in the homework forums, repeatedly asking for answers and not explanations nor help to understand the problems. This is a bit of a turn off somewhat. It's different if people ask for assistance and are prepared to follow leads and try it themselves, but, a few (a minor few) just ask for answers and get quite demanding when ignored!
Anyway ....I've enjoyed it and would recommend it but be prepared for more hrs work than they say. Maybe I'm just older and slower than the young'uns!
