Below you can find out which chapters and which paragraphs are written for your profile. The titles on the left are buttons to take to that page. On the right, an indication is given on how long you'll probably have to work on the exercises, that'll help you plan a bit better.
On the pages themself, some parts might be adorned with a little icon as well. That part is just for that group of students. When in doubt, ask your teacher.
The parts and pages specifically for Biology and Physics are interesting for the students who have chosen that subject but they won't appear on the test.
When you're done, ask your teacher what you can do.
