I managed to download the update for the 1st semester after clicking restore many many times. It seems like it will download a bit and then it will time out. Everytime it time outs, it will show the restore button which you will need to click again. My internet speed is 100MBPS from Starhub so I don't think it's an internet speed problem. My ipad have around 50GB free space so it's definitely not that. Still trying for semester 2.
To lelask, the udpate is doen from the app and not from itunes. Go into the app and click on "download lessons." Tghen click on the lessons you want to update.
Can Lappy or Kezia pleases give us an updatte when it's available?
