After the self-study exam, you still need to find a test center. General test sites will be located in A-level teaching institutions. You can choose a major and take the exam there.
For Cambridge, I can tell you for sure that it is quite difficult! After the results are submitted in the first round, there will be two rounds of elimination, including step3 math test and interview. As for the admission rate, it also depends on the major. You see, there are so many people studying A-level in China. There are many great gods in our school who can get an A without listening to lectures, but not everyone can.
Secondly, the difficulty of the course, regardless of mathematics, although the difficulty of physics and chemistry is much simpler than that of domestic high schools, most of them are text questions, and pure calculation means giving points. Cambridge needs AAAA *, or AAAA can do it. It depends on what major you are applying for. If you want to study mathematics or engineering, further mathematics is required, especially the mathematics level of the university. The average FM score is around C, but Cambridge requires A *.
Don't worry about my grades now. When I first started learning A-level, my math was average. My class is slightly above that, and it was only 89 when I took the chemistry senior high school entrance examination. But now chemistry and math are my best subjects.
In addition, in recent years, the British Council and CIE are under increasing pressure, and the probability of getting an A is getting lower and lower, which will lead to mistakes. I have a classmate who has always been a in physics and finally got a D. This will happen, and it will take a lot of money and time to apply. It is better to retake the exam.
Ps: I suggest you don't demand such high standards. Cambridge is not the only good school in Britain. For example, in engineering, Imperial College is the first; Business, the first to promote London politics and economy; And UCL's architecture is the first in Britain. You must choose a major now. British universities all need required professional grades. For example, if you want to study business or management, it is useless to take the physical chemistry exam.
Because four circles are tangent,
Therefore, the intersections of tangents O65438+OO3 กอ and O2O4กอ with tangents are E and F, respectively.
