SDD was a class I looked forward to....once cable was installed and there was the Video Editing Room where the comps didn't have any restrictions, were only used by the 8ppl in yr12 SDD and were capable of running recent games, the C drive was filled with 30gig of downloaded games. Though we only managed to pull off a full lab CS game once as the prinicipal walked past and was not happy.
On the lessons were work was done, we would do 10mins work and then take a 10min break, crappy flash games were popular here.
Of course all this assing about meant we left all the work to be done at home, so in the end it's basically just taking the time you would of had free at home, for me it was worth the trade, SDD class had everyone laughing on the floor every lesson, great memories.
