The students are studying ahead during the holiday.
IB Chemistry and Biology require plenty of materials.
Past-paper and IA resources need to be well organized.
The image above shows the Biology summary notes I compiled.
We study the notes and work through around 100 past-paper questions a day.
The Biology summary is about 80 pages.
That leaves most of the time for past-question practice.
The image above shows collected Chemistry past papers, with questions and answers from 2009 to 2018.
I split the answers into several sections.
Finally, the image above shows the question book compiled from past papers.
I included details such as the topic and year.
I prepared it separately to make it as convenient as possible for students.
