Hi all,

I made a google classroom that is categorized into 6 modules for covering some interesting questions in IB HL.
what I'm trying to do is to give you guys questions for each topic, hopefully every day. And I will always attach video solutions for them.

Hopefully you will get some help by the classroom. Any comment/advice will be much appreciated. Thank you!
