2、考前心理準(zhǔn)備成績(jī)優(yōu)秀的考生應(yīng)記住：“沒有常勝將軍”、“不以一次成敗論英雄”；成績(jī)不太好的考生要有“破釜沉舟”的決心。

3、高考當(dāng)天早晨，應(yīng)有良好的心理暗示如“我很放松，今天一定能正常發(fā)揮”、“今天我很冷靜，會(huì)考好的”等。

4、注意早餐早晨一定要吃豐盛的早飯，但不能過于油膩。

5、瀏覽筆記、公式、定理和知識(shí)結(jié)構(gòu)主要是瀏覽一下重要的概念、公式和定理，或記一些必須強(qiáng)記的數(shù)據(jù)。

6、進(jìn)考室前10分鐘在考室外最好是一人平靜地度過，可就近找個(gè)地方坐一會(huì)兒，或看一下筆記，再次瀏覽知識(shí)結(jié)構(gòu)。設(shè)法避開聊天。
