1984, high schools all over the country have fully recovered, and the first college entrance examination has been ushered in, so the proposers this time are all academicians or top professors in China. The angle of the topic is very unique. At that time, everyone was memorizing formulas. Reciting the template, I didn't expect it to be completely bad this time At that time, the wrong answer to the math physics question may be deducted, which may be unimaginable now. Therefore, such criteria will make many candidates crazy and dare not write answers casually. Many students may gain something from the big questions, but because of the wrong choice of multiple-choice questions, the two eventually cancel each other out, and their grades in mathematics and physics are not ideal. Since 1984 college entrance examination was criticized by many media, the college entrance examination in China has gradually returned to the right track, the difficulty of college entrance examination questions has been strictly controlled, and a strict statistical system of difficulty coefficient has been formed. The college entrance examination questions are randomly selected from the question bank.
