I believe they do not judge you by what science you took for
your o levels.
The thing they judge you is by your L1R4/L1R2B2, i.e. your
aggregrate.
Difficult of not depends on your on well you studied in your
secondary school.
I will say if you really want to take aeronautical engineering,
make sure your physics and mathematics understanding is good, to
the point that i recommended that you study pure science or pure
physics or at least have a very strong foundation on physics if you
intend to enter aeronautical engineering.
Aeronautical Engineering in Poly is basically a Diploma focusing
on the Mechanical side of Engineering, just that they are teaching
you aircraft structures and other aircraft systems.
The reason for the need of strong physics foundation is because
most likely there will be lots of physics like thermofluids,
pressure, bernullio's eqn(however it is spelt), kinematics,
dynamics, energy etc. I have took the module physics and scored
badly, the syllabus taught to me is the same as A level physics
I am not from aeronautical engineering, but i have took one of
their modules called aeronautical engineering science/fundamentals
of flight.
It was the hardest module ever! It requires me to learn other
mathematics from elsewhere to solve part of the problem.
But overall, i believe aeronautical engineering will be a very
interesting diploma to take, and what you learnt from this diploma
will give you the knowledge to attempt the SAR 66 paper to become a
licenced aircraft engineer
Note:
Please do not confuse Diploma in Aerospace Electronics and Diploma
in Aeronautical Engineering. Many people have queries on the
difference between the two.
Diploma in Aeronautical
Engineering is more on the mechanical/aircraft
structure side. It is generally more mechanical, i am not very sure
about the details as im not from aeronautical engineering.
Diploma in Aerospace
Electronics teaches you generally the electronics
side, like autopilot system, aircraft servo mechanisms, aircraft
landing system, the gyroscopes, sensors, how the electronics and
feedback help to keep the trim tabs and flaps at position that will
keep the aircraft straight and leve, and everything electronics
that warn the pilot.
And ya, both the course will not enable you to be a pilot, if
you are interested in becoming a pilot, please take the Airline
Pilot Transport Theory Course
Hope your idea of aeronautical engineering is right!
