Thanks Ultima,
i've heard of your awesomeness throughout the homework forum, so
BTW the topics in Sec 3 and 4 are which ones?
Sorry about my 'A-holeness' i've been cheoing my a-maths even
though mid-years over so i'm really too exhausted to study
chem.Really, really sorry
Hi SgStudentStressed,
Chemistry is the Central Science, and both Physicists and
Biologists need to work with it to some extent, which is why I'm
keen to promote students' interest and deeper understanding of
Chemistry.
It is never too late to start cheonging Chem. Specifically, you
have to ask yourself what future profession of interest, and
accordingly, your University course of interest is. If you're
looking into a Science-based career and University course, then you
should definitely cheong Chem, together with *either* Physics or
Biology. (Due to the contrasting subject requirement in the new
H2/H1 JC system, it is difficult to study Triple Science these
days).
If engineering is your interest, Physics is the other important
subject you need to focus on. If biological sciences is your
interest, Biology is the other important subject you need to focus
on. Either way, ensure your Chemistry is strong, so as to keep more
doors open, University as well as profession wise.
As for chemistry calculations, you may be asked to do them in
*any* topic of chemistry, which is why your calculations foundation
need to be strong, or you will suffer across topics.
You can check out my list of questions in my two threads (url
below). The questions I've indicated as applicable to both "A-level
and O-level", are almost always chemistry calculations questions.
In fact, the most common Challenging Qns that can be
asked at O levels, are the chemistry calculations qns
which are considered easy or standard difficulty 'A' level
chemistry calculation questions.

If you really want to cheong and master chemistry
calculations, you can consider buying an 'A' level Chem practice
book (eg. CS Toh's 'A' level Practice Qns) and practice all the
chemistry calculations / stoichiometry questions in the book.
Of course, if even the basic 'O' level chem calculation qns are a
problem for you, then do not buy 'A' level chem books, they may do
more harm (discouragement) than good.
If you find yourself with a keen interest in Chemistry (or any
particular subject), do consider becoming an MOE teacher in future,
and share your appreciation, deeper understanding and love of
the subject.
Many of my chemistry students went on to become MOE chemistry
teachers, following in my footsteps. Share the joy forwards.
