Once registered for your CAO..... You must complete your course options before 5.15pm on February 1st 2010 online @ www.cao.ie to avoid late change of mind fees. Talk to your school guidance counselor if you are still unsure of course options. The website Qualifax is great for researching course information. Don't leave it until the last minute, the CAO website can get very busy in the lead-up to the closing deadline!!
