What is this class about?
During the 10th grade, students take IGCSE (International General Certificate of Secondary Education) classes, also known as PRE-AICE. The overall goal of Pre-AICE classes is to prepare students for the rigors of AICE classes.
This class was prepared specially for you. Here you will find everything you need. Notes, assignments, quizzes, labs, videos with explanation of some topics, etc.
Is chemistry hard?
Many students are scared about this class. I'm here for you , to help you every time you need it. I cannot tell if you have a question unless you speak up. Please do so.
How can I avoid getting behind?
This is an IGCSE class. That means that we will have homework and or lab reports to complete every week.
What do I do if I have problems with my homework?
Again, I'm here for you. Please check with me if you do not understand how to complete the assignments or exercises. We can arrange some time to see it together before or after school.

IGCSE Syllabus For examination in June and November 2019-2020-2021
Assessment Methods used for Pre-AICE
At the end of the year during May and June, students are required to sit external exams for all of their pre-AICE subjects. The dates for these exams are set by the University of Cambridge, so on occasion fall outside of the regular US school year. Students are expected to attend all exam sessions.
The papers are then sent back to the UK for marking and we usually receive the results in early August.
Cambridge exams are designed to test students ability to apply the knowledge that they have acquired during the year.
There are three exams they need to pass:
Paper 21 – (ex paper 1, or 11) – 45 minutes – 30%
A multiple-choice paper consisting of 40 items of the four-choice type. This paper will test assessment objectives AO1 and AO2. Questions will be based on the Extended syllabus content (Core and Supplement). This paper will be weighted at 30% of the final total mark.
Paper 41 – (ex paper 2 or 21) – 1 hour 15 minutes – 50%
A written paper consisting of short-answer and structured questions. This paper will test assessment objectives AO1 and AO2. Questions will be based on the Extended syllabus content (Core and Supplement). 80 marks This paper will be weighted at 50% of the final total mark.
Paper 61 – (ex paper 6) – 1 hour – 20%
Alternative to Practical This paper will test assessment objective AO3. Questions will be based on the experimental skills in Section 7. The paper is structured to assess grade ranges A*–G. 40 marks This paper will be weighted at 20% of the final total mark.
