Give me some of your opinions and tips regarding class 9

So, I got into class 9 this year and all I’ve heard from parents and close relatives is that this is the class where you mourn your childhood because there’s no such thing as December anymore, too much study pressure and stress due to ssc exam etc. I want to hear your experience regarding class 9, what was it like? And what are some things I should consider at this class to enhance my experience, if any?
