When I started developing apps on my own, I didn't have a clear understanding of how to add ads to my apps or how to develop them, but this course was very helpful. In particular, I was able to clearly define my goal of gaining experience by trying as many things as possible as quickly as possible, and I was able to gain insight into changing my perception of ads and exposing them appropriately while making sure my app provides enough value. I'm looking forward to the rest of the course!
