Actually i'm not from a top jc. In fact, the basis for my
concerns lies exactly in the fact that 70 is already considered a
shaky grade even in neighbourhood jc. Imagine what top jc students
(a majority of which has higher aptitude in chemistry than me) can
do if above 70 is a common norm for neighbourhood jcs in the A
levels.
@Ultima, thank you very much for your response. I really
appreciate it. Undeniably, i would have appreciate it more if your
response had been made with kinder words. Given the fierce
competition in the Singapore education system, i believe that there
is sufficient basis in enquiring on the prospective grades that
could be attained with my score, since i believe strongly that
there will be a bunch who will be attaining a similiar score.
70% overall score *isn't* a common norm (ie. majority) for
neighbourhood jcs (top to mid-tier JCs, maybe; neighbourhood JCs
imply bottom-tier, for which 70% overall and/or A grades, are the
minority) in the A levels. Only the top JCs have A grades as the
majority. Overall (entire cohort ; by definition, top tier JCs =
33%, mid-tier JCs = 33%, bottom-tier JCs = 33%), B grades are the
majority.
And I wasn't trying to be mean, but I did mention (many times in
this thread already) that the *overall* (ie. regardless of how
badly you do in any individual paper, let alone your 70% for your
worst performing paper isn't bad at all) % for A grade boundary is
75%, and your own estimation is a 80-85%, so there was really no
need for you to even ask, but your insecurity got the better of
you.
I reiterate : 75% overall is sufficient to get A grade for H2
Chem (if you calculated you got 75% but it turns out you didn't get
A grade, it's because your SPA must have pulled you down, or you
didn't realize you made some careless mistakes in other questions,
or trusted your school's answers too much, naively assuming
Cambridge will definitely give it full marks, etc).
