GaoKao needs to be hard because there are too many students in china and not enough good schools. if GaoKao is easy then everyone is going to the Top 10 University in China
Bill Guo I agree but schools want to maintain their prestige by admitting less qualified students. This is a phenomenon practiced in every part of the world. In addition to that, the overall Chinese student population is very focused on academics.
From an engineering student who ever failed physics at university, I'd say the questions are not untypical. In the regions like Beijing, Shanghai, Guangdong, the exams would be harder.
Question 3 can be easily handled with nodal analysis rather than focussing on series parallel combination or charge flow method question 1 is mostly present in all high school textbooks Gaokao's maths section is quite good As good as jee advanced 👌
First problem is stuff you should be using all the time, at least if you're a physicist. Getting time and space mixed up isn't good, though I'm sure I'd make the same mistake 50% of the time.

This stuff is your typical intro physics classes that the professor probably forgotten because he doesn't teach Physics I/II. Kinematics, circuits, and intro relativity topics are what he took classes about these things during his first year of physics in undergrad (if not earlier)- and probably not relevant to the phenomena he studies or the upper level physics he teaches. What i can also comment on is the backwardness of the Chinese education system from elementary school to PhD programs. I was a teacher in a medical school in southern China (teaching medical terminology and neurobiology) and can personally attest to this.
Believe me those questions were of jee mains level. For those who don't know that's a test you give to get qualified for JEE ADVANCE!!!!!!!! Except that relativity one because that's not in the syllabus of jee
In fifth question correct answer is A, not A and D. Answer D is: Ta ^ 2 / Tb ^ 2 = Ra ^ 3 / Rb ^ 3, where Ta, Tb - periods of a and b; Ra, Rb - radius of a and b. Let's check it. We have formulas for periods of a and b: (1) Ta = 2 * pi / wa; (2) Tb = 2 * pi / wb, where wa, wb - angular velocity of a and b. We know that acceleration in circular motion is: g = (wa ^ 2) * Ra and g = (wa ^ 2) * Rb; (3) Let's square (1) and (2) and replace squared angular velocities with help of (3) (wa ^ 2 = g / Ra; wb ^ 2 = g / Rb). We will get: (4) Ta ^ 2 = 4 * (pi ^ 2) / (g / Ra); (5) Tb ^ 2 = 4 * (pi ^ 2) / (g / Rb). If divide (4) by (5) and make reductions we will get: (Ta ^ 2) / (Tb ^ 2) = Ra / Rb.
Brother I wish you had some knowledge about how universities are ranked....Many criterias are considered which are not applicable for IITs ,like there is a criteria where the number of abroad students studying are also taken in account where all the iits have been awarded a perfect zero as students from abroad are not allowed for most of the degrees as well as the countries literacy rate and developement are also considered which obviously India as a whole is very very poor.

From an Indian perspective Questions looks easy.But i was surprised to find special relativity questions at high school level entrance exam.I think the paper setters in china are actually testing how MUCH they know.The Indian paper setters on the other hand test how WELL they know.Which is why 70-80% of questions will be from Newtonian Mechanics,Electrostatics and Thermodynamics.You will hardly find any questions on modern physics.
