The Different Strokes
(a comparision between CBSE Boards and competitive examinations)
The same syllabus, same students, the same hard work,
but different results !!!
It had been intriguing, all the time, for all the
students. But as soon as we understand, ?how it
is that same syllabus is being asked differently
in different exams?, our efforts will be different
for different exams and results will be uniformly
BRIGHT (Good). In other words, there is
absolutely no difference in the concepts involved
in the questions asked in the various board and
competitive examinations. The difference comes
in the way, it is asked in these exams. Wherein
the boards, they check the conceptual clarity of a student, in the competitions,
it is the application of the concepts which is stressed upon. Further this
application skill may vary from exam to exam. For Example:
I : Projectile motion
What they ask in CBSE ?
Q1 (a) What is a Projectile.
(b) Find out the maximum range & maximum height for a given
velocity (u) & ratios there of.
(c) Find the range of a Projectile falling from a horizontal table
etc.
What they ask in AIEEE/ PMT ?
Q1 (a) What is the minimum Kinetic Energy of the projectile with
initial velocity (u) & angle of projection (j), mass of the object
being (m) ?
(b) How much time it would take to reach a height ?h? ?
(c) What should be its velocity at height ?h? ?
[HINT: Calculate from basic concepts. No direct formula used.]
What they ask in IIT-JEE ?
Q1 (a) What is the height (hm) & velocity (Vm) of a projectile when
angle between the initial velocity and velocity at hm is
perpendicular to each other.
Vm
hm
v
q
q
(b) If a projectile has a range of ?R? & there is a high wall at a
distance (d) from the point of projection, at what distance will
the projectile strike on the ground after being reflected from
the wall with inelastic collision (e being 0.8).
o
e = 0.8
d
R
(c) What should be minimum velocity of projectile so that it hits
a aeroplane at a height (H) which is moving horizontally with
a velocity of u .
H
u
What they ask in IIT-JEE ?
Q1 (a) Find the ratio of T2 '' & T1' ' at an inclined plane of angle of 32º,
when pulled with a force of F=120 N, upward.
32°
120N
T1' '
T1''
T2' ' T2 ''
[Hint: Force drops in ratio of masses & independent of angle. Hence T 1 = 60 N, & T 2 =
24 N]
What they ask in CBSE?
From the above examples, we find that ? syllabus is same, topic is
same, but there is level difference in asking & Calculations. Hence we
can conclude that:
CBSE asks straight forward Questions to TEST the knowledge.
AIEEE asks the application level questions but simple calculations.
IIT-JEE asks analytical ability & depth in the Concepts & some times smart
calculations.
For the better understanding of the above article we can use the anology
of VEHICLE DRIVING CAPABILITY.
CBSE.ASKS : What is accelerator, clutch, Brake, Steering, self-ignition &
steps to use it in driving.
AIEEE ASKS : OK drive forward, left, right, backward etc. & some times
can ask the role of clutch & hydraulic braking systems.
IIT-JEE ASKS :Let as take our vehicles, on the road & drive through a stretch
of ten kms through traffic conditions, bad patches, & various
turns. Those who reach first with reasonable time know the
Driving well & the rest are rejected.
That is Selection on the basis of application Skill.
Hey guys, the above art, isn't self-composed bt found motivating-hpoe u lyk it.
