Hi, I am a poly grad with a diploma in biomedical science, GPA
of 2.22. I am currently in the last few months of my NS. I am
seriously considering taking up private 'A' levels, so that I may
have a shot at going to university(hopefully a local one). I was
wondering if i could get any reccomendations on which institutions
provide good, structured classes for taking private As.
Also, what is the minimum number of subjects required to be
taken and could someone kindly explain the H1/H2 system.
Thank you,
Don
H2 subjects are double the syllabus content, and thus double the
weightage, of a H1 subject. Almost all JC 'A' level students
take 3 H2 subjects and 1 H1 subject, and a minority
(those more capable) will choose to take 4 H2 subjects,
which has the advantage of choosing your weakest subject's results
(ie. after you've got your exam results) and downgrading them
to a H1 weighting, when calculating the University Admission
Score.

In order to study BioMedical related courses in the University
(assuming that's your intention), you will need to register
for H2 Chemistry, H2 Biology, and H2 Mathematics. Furthermore, your
BioMedical diploma would already have prepared you well for H2
Biology, so that subject would be an obvious choice. If you intend
to take up engineering courses, then you will need to substitute
either H2 Chemistry or H2 Biology with H2 Physics.
As local Universities (eg. NUS, NTU) require a contrasting
subject (ie. non-science, if all your other subjects are
science-based), you should take H1 Economics (or some other
non-science subject, though Economics is generally regarded as the
most commonsense, practical and thus popular).
In addition, you will require H1 General Paper, which basically
tests your English, writing and language communication skills.
As for whether it's necessary to take a H1 2nd language, as well
as a possible additional H1 subject in lieu of Project Work, can
someone else (eg. ChemGuide) comment on this?
