Science and engineering examinations are among the best, with one for most engineering and science examinations, two for biology, chemistry, environment and food, and three for economic management.

Number one: high number, modern, probability, basically all tested.

Number two: probability theory is not tested at all, advanced mathematics (spatial analytic geometry and vector algebra, triple integral, curve and surface integral, infinite series are not tested), and line generation (vector space is not tested).

Number three: advanced mathematics (space analytic geometry and vector algebra, triple integral, curve and surface integral are not tested), line generation (vector space is not tested), probability theory (interval estimation and hypothesis test are not tested)
