This is how it's supposed to go:
2012: Year 1 SBC and other Year 1 intake. Students across this batch will enter Year 3 IP in January 2014, entering Year 5 ACS(I) IBDP in January 2016 and graduating December 2017. Technically then, this year's Year 1 intake will be the first joint MGS-ACS IP batch, although they didn't start out as IP.
2013: Inaugural Year 1 IP batch, based on SBC. Will be IP all the way, entering Year 5 ACS(I) IBDP in January 2017 and graduating December 2018. Technically, this batch will be the first completely IP MGS batch.
Where is your source of information? I've been waiting for more info on this.
So you mean ALL students from Year 1 this year in MGS will enter into the IB & IP program when they are Sec 3 in 2014? But i thought some will still do the O level track. I thought they need to take the HAST test again?
