It seems like you have provided a detailed plan for the revamping of your school's student council and extracurricular activities. Here are some key points that stand out from your document:

1. Student Council Reform: You propose to restructure the student council by establishing an internal committee and adopting a new election system, which will allow for more diverse representation and encourage students to participate in decision-making processes.
2. Extracurricular Activities: You plan to introduce new activities and modify existing ones to cater to different interests and preferences among students. This includes the addition of new sports, such as skateboarding and roller skating, and the implementation of a trial period for ECAs to allow students to try out different activities before committing to them.
3. Communication Channels: You propose to establish multiple communication channels, including Gmail, IG, Google Forms (for anonymous reporting), YouTube, Google Sites (official webpage?), and WhatsApp/Social Media Groups, to facilitate student participation and feedback.
4. School Policy Improvement: You suggest opening up the fifth floor rooftop for multiple uses, such as art classes or astronomy club meetings. Additionally, you propose to establish a new activity area for students to take breaks and socialize during class hours.
5. Trial Periods: You plan to hold trial periods for extracurricular activities in September-October to allow students to get familiar with different activities before committing to them. Each activity will have two to three lessons, with the first lesson focused on team-building and group games.
6. Diverse Teaching Content: You propose to incorporate more diverse teaching content in PE lessons, such as skateboarding or roller skating, which may serve as an alternative to their respective ECAs.

Overall, your plan appears well thought out and focuses on increasing student participation and engagement in decision-making processes, as well as providing a more diverse range of extracurricular activities.
