You should expect a lot from GYEL! You will learn so many new things that will allow for you to make a long lasting impact in the world and your community.
I would advise you to participate and attend office hours because you will be able to engage with other students and the instructors, allowing for you to learn more and become more involved.
A change making mission that you should join should be based on whichever SDG you feel most connected to and most passionate about to explore and learn more about and create an impact.
