It is highly not encouraged. While you can access SLS from internet browsers installed on your mobile phones or equivalent devices, the system is currently not optimised for use on these devices. Use devices with screen size larger than 7 inches for good user experience and to ensure that you do not over strain your eyes.

You should take turns with your siblings when sharing devices. Priority should be given to the one with live lesson. You can seek your parents's help in making arrangements. 

Stay calm, click on the refresh button at the top of your browser. 

If SLS website is still lagging or slow, you may try again later. 

If the SLS system is down, do not worry, you can attempt your learning the next day.
