Your title question was "any CIE-Cambridge 'A' level physics
student here?", to which the unspoken answer is "no, only
Singapore-Cambridge 'A' level physics students and tutors
here", which is why no one replied your thread.
If instead, you're asking for help on 'A' level Physics qns, you
could just have posted the physics questions
directly here, and probably received replies and help for your
questions by now.
I'm a Chemistry person, not a Physics person. But if the
syllabus differences are similar for both physics and chemistry,
then a Singapore 'A' level Physics student/tutor should
still be able to help you with most questions from the CIE 'A'
level Physics syllabus.
So why doncha go ahead and ask whatever you wanna ask, ie. your
purpose for starting this thread.
