Is your school further back in the material? No problem!
You can watch the recording of a given topic on our platform (we have covered all sections of the textbook since the beginning of the school year).
If on the other hand your school asks you for an exercise that you don't know how to solve, you can ask out teachers and assistant on our Discord server for an individual help.
In any case, you can also ask your question in the classroom - you never know who else in the group may have the same issue!
