I also noticed the similarity between Questions 18 and 20. Then I
noticed that Question 18 is from the test administered in 2003, and
Question 20 was from 2004. I don't understand why they chose to release
two questions that are so similar.
There are also several problems with the reference sheet, which is
included after the questions.
1. The same symbol, v, is used for both average and instantaneous speed.
2. The equation for Newton's Second Law does not indicate that it is the
NET force that equals ma. In fact, the same symbol, F, is used for net
force, centripetal force, and gravitational force.
3. The same symbol, E, is used for both kinetic and potential energy,
and this symbol is not commonly used for either quantity.
4. The equation P = IV is identified as "Power Dissipated in a DC
Circuit". The same equation applies to a capacitor being charged by a
battery, in which case, the power is not dissipated.
5. Units that are multiplied together are separated by spaces, rather
than dots.

How about questions 18-20? All three are similar. Number 18 states
that pressure increase is related to temperature increase and asks why.
How is this different from #20:
