I had used communication skills multiple throughout my life in IB, ranging from simply sending emails to teachers to managing and interacting with year 5 kids in my enrichment. I make sure to communicate with most of my teachers and talk to them/ask them whenever I need help, and I also speak about my problems/concerns or questions whenever I am discussing with other people. Communication is one of the most required skills needed in IB, and it is a skill that I use daily.
