It's detailed in the "Shoulder To Shoulder" NS Journal book they

library if you can't borrow a copy yourself.
The physical examination decides your PES classification. It's
modelled on the British PULHEEMS system...
P - physical characters (height, weight, etc.)
U - upper limbs
L - lower limbs
H - hearing
E - eye, right
E - eye, left
M - mental state
S - stability
...plus one additional checkup item (dental condition), according
to the book. The procedure's also supposedly made more transparent,

health counselor available nearby for follow-up enquires.
The aptitude test is officially called MAPAS (Manpower Aptitude
Assessment). It's computer-administered & seeks to assess the
cognitive ability to process information quickly & accurately:
memory, speed of response, abstract reasoning, ability to follow
complex instructions, ability to solve mathematical problems,
mental spatial ability, etc. I understand it can take quite a
while, but there's no reason to get panicky over it.
