math you die die also must remember what is the formula and how
to apply it.
knowing formula but not knowing how to apply = not knowing at all.
so its best to practise for these kind of question....
for theory stuff... i will read through the whole topic once then
copy the important stuff and linking keywords with them.
if there are too many points, i will shorten the keywords to only
their first alphabet. eg, APPHG <- dun make any sense but i
remember it and recap what that alphabet stands for. and the
information will naturally flow out.
