yo! i didnt do well for my h2 econs for all my exams. i got an U
for my mid years and an S (after moderation) for my prelims in J2.
However, i didn't give up on my Econs still (despite the lousy
grades) and went ahead for consultation with my tutor (it's REALLY
HELPFUL!) and i scored an A for my Econs A levels.
Trust me, go for consultation. Do an essay a week (or one essay
every two weeks if u are lazy like me) and let your tutor go
through with u in a small group. it was very helpful to me. Try
taking down notes about how to attack an essay question as
well.
Always remember to score the two evaluation marks for each essay
(part B or the 25m essay qn). then, always manipulate your answers
until it sounds like a L3 answer (read the answer scheme and u'd
know what i am talking about) and u'd get high marks for your
essay. (lol)
for case studies...well..cant say much. i always suck at case
studies.
=) my 2 cent worth. hope it's useful to u
