Hi,
I have 18 sets of 2009 GCE O level Prelim Social Studies
papers from 18 schools. Each set consists of the question
paper and answer provided by the school. If you are willing to take
all, there will be a complementary collated SEQs 2009 Prelim
questions from over 60 schools for free. If willing to take all, it
will be $35
I also have 19 sets of 2009 GCE O level Prelim History
Elective papers from 19 schools. Each set consist of the
question paper and answer provided by the school. If you are
willing to take all, there will be a complementary collated SEQs
2009 Prelim questions from over 30 schools for free. I willing to
take all, it will be at $35
*If you are willing to take all the 18 sets of SS and 19 sets of
History Elective papers, there is a special price going at
$60
I am also selling Biology notes that could use in O level exam 5094
(Pure Biology) and 5117/5118 (Combined Sci (Bio)) in the year 2012
and 2013 (no change in syllabus)
The bio is compiled by a group of students and is vetted by a
teacher in the school.
The notes are arranged in this order:
a) learning objective for the chapter (taken from the syllabus
outline on SEAB website)
b) sumarised answer to that learning objective
For example, in Chapter 10: Homeostasis
b) Explain the basic principles of homeostasis in terms of stimulus
resulting from a change in the internal environment, a corrective
mechanism and a negative feedback.
A stimulus is
a change from
the normal condition
of the internal environment. Receptors detectthese changes in
the internal environment. Impulses from the receptors are sent to
the control
centre or regulator, triggering an
appropriate response to
restore internal environment to the norm.
A response counteracts the
changes and returns the
internal environment to the
norm.
This may be behavioural,
such as moving into the shade avoiding the heat of the Sun,
or physiological,
such as an increase in the blood glucose levels. This response to
return the internal environment to its normal levels is known as
negative feedback.
In addition, the key words are being underline and new terms are
being bold.
This will ensure you are on track on revision for biology and know
what Cambridge exactly wants from you.
These notes are extremely useful as you do not have to read your
textbook for information again.
I am selling the notes for Pure biology
at $10 and
combined Sci (Bio) at $8
For all of the items listed, if you are willing to send through
mail, postage fee will be free but you have to do fund
transfer.
Meet-up for collection are fine also well.
