today's common test paper was a lousy paper.
damn lousy, with no logic.
i made me feel so discouraged and demoralised after doing the question 5
the question itself was ambiguous
the question asked if how many different ways can the student study for his maths test,
if there were 10 topic including differentiation and he only study 3 topics a day.
mr go's answer was 10C3
his reasoning was: normal people will assume that the question is asking for each day.
however, the question did not clearly state
if the student the number of ways he can study for his test EACH DAY
my ans was 10C3 X 7C3 X 4C3 X 1C1
basing on the restriction given that he only study 3 topics a day
but, he argued that if that's the case,
on the last day, the person will only study one topic which did not fufill the restriction
if that's the case, the ans will be 10C3 X 7C3 X 4C3 X 1C3
in which 1C3 is not defined
so what will be the final ans?
his reason was very ridiculous which i can't accept
teachers kept emphasising to us that do not ASSUME
yet he said that "normal people will assume"
i cannot believe this
basing on my assumption and interpretion of the question,
the subsequent parts to the question could not be done
hence, i left it blank
reason being he has to study all topics, he canot leave out any topic
although in life experiences, there are people who do not study everything,
but we shouldn't base on the students' psychological aspect to the question
we are doing AMATH not PSYCHOLOGY...
the question is a total of 3 marks
and because of the question which left me in deep thoughts during the test,
i did not complete the paper
i believe my assumption is much more logical
and that's my personal opinion
keyword: personal opinion
hence the source is not RELIABLE
i argued with ms tan in class
and i know that my tone was a bit overboard
sorry.
maybe next time the setter should just state clearly what he wants
and not make such misunderstandings in future
like always in those content-based subjects
they penalise us if we did not state CLEARLY.
CONTENT ABOVE IS MY PERSONAL OPINION
black and white.
