Cost of teaching CAT

Computer Applications Technology must be the most expensive subject for a teacher to teach, with respect to personal expenses. You have to have a computer at home for all the lesson preparations, exam marking, etc. This year I have had to have my laptop repaired R1000, buy a new laptop R7000, pay for the Internet SuperUser course R6000, pay someone to help me mark as I could not cope with the time limits R2500, as well as sundry amounts. All from my own pocket! I have just had a burglary and will now have to buy another new laptop, printer, get an ADSL modem, etc. i.e. replace all the computer stuff again. Must be made of money, just to teach Computer Applications Technology.
