IGCSE考试紧锣密鼓的进行着,相信大家都在努力备考中。关于化学学科的复习以及最后的冲刺,老师整理了一些干货分享给大家,希望能够帮助大家梳理知识点,从容应对考试。
IGCSE化学试卷分为core和extened。如果选择core需要答paper1,paper3,如果选择extended需要答paper2,paper4。Paper5,Paper6是实验部分。
具体考试形式是:
Paper 1: Multiple Choice (Core)
Paper 2: Multiple Choice (Extended)
Paper 3: Theory (Core)
Paper 4: Theory (Extended)
Paper 5: Practical Test
Paper 6: Alternative to Practical
无论是学习拓展课程还是核心课程,学生都要考三张试卷。学习核心课程的学生考试卷1和试卷3以及试卷5或6,学习拓展课程的学生考试卷2和试卷4以及试卷5或6。
试卷1和2为选择题卷,一共有40道选择题,考试时间为45分钟;试卷3和4为理论题卷,主要是简答题和结构化问题,所有题目都是必答题,考试时间是1小时15分钟,满分80分。
试卷5和6考查的都是实验技能,区别为试卷5需要进行实际操作,试卷6以笔试形式进行。
