pure biology and combined science ( physics +
chemistry)...
content wise...
let me break it down...
in combine science each of the sub science subject;
example: sub physics is content wise 75% of pure
physics
but questions set on sub physics papers are easier
but if youre taking one pure and another two combined like me, I
advise you either take two pure (meaning keep your pure and choose
the favourite of the two sub) OR take three pure, if your school
allows.
Why I say that? Because its pretty much the same thing only
harder, but as a student when you study, you can lump the 3
sciences and study one after the other. WhI dereas one pure the
other combined is confusing and not very satisfying.
But personally... Id rather choose 2 pure, but since I dont
have the oppurtunity... Im having my combination of pure bio and
the other two sub. Atleast in a sense Im taking triple sciences,
and for me its satisfying.
