: 1. J.J.M的那4套"假题"还看吗?
Don't do it! They have negative effect on you probably. IN my view,
those questions are junk because their focus are not basic concepts and
methods which is what ETS want to test.
: 2. 近几年的物理专项与88年附近的难度与考试范围改变大吗?
Much difference! Since the old problem database was invaded by someone
in 1993 or 1992, ETS has rebuilt its new database. They also extended
the test area and made sub more difficult. For example, topics in modern
physics, such as Quantum Mechanics, Stat. Mechnics, are covered in many
questions more than before. You must be farmiliar with solutions to
schrodinger equations for one dimensional potential well and harmonic
oscillator. I don't mean remeber the form of the solution which may be
helpless on test. I mean that you must understand the basic ideas behind
the wavefunctions.
There are a few questions related to the front research directly. Such as
the experiment on Bose-Einstein condension.
One must go over all the materia thouroughly if want a full score.
Remember, your competitors are not Americans who don't care much on it.
