nicole77 Just wondering if it's worth changing schools or not
Well, what's your motivation for exploring JMSS as an option? Are you happy at your current school? How far away from JMSS do you live and is it realistically viable you travelling to and from there on a daily basis?
The answer to 'is it worth it' depends on your own circumstances - some of which you can identify by answering the above questions to yourself (you don't have to publish them here).
Acceleration at Year 10 is a good option if you want to stay - it also means you do a Unit 3/4 in Year 11, making it one less subject you have to do at Year 12.. which is always a good thing, less of a load to take on in your final year.
