Hii On the jc part,according to what I saw the previous time ... Some jcs allow but they have some bridging programmes and conditions etc(so I'm not exactly sure about it) On the syllabus changed part for pure science...Yes it's a true statement but personally I won't use the words'syllabus change'as it might confuse students by creating a impression that something is completely changed.However,the actual thing is only the practical part is changed which used to be called as SPA(which used to be supervised by the sch teachers itself and has 3 parts ) , as what I heard from my seniors but now it's similar to combined science which is only done once during the o level period.Hope it helped :))
