Maybe you took an interest in enough things to do well? Personally, I’d get distracted from lessons with trying to figure out alternative ways to think about or solve problems for things like math and I liked practicing mental math, so used normal classwork as a way to do that.
More surprised I was able to deal with classes like English and history though. But I’ve just been lucky enough to have a good memory for certain things school cares about.
The lack of groups was the deal breaker for me, so after it rolled out to beta, I finally switched back to Firefox as my primary browser.
Last I tried, I don’t think you could reorder or drag/drop groups and selecting multiple tabs doesn’t result in “group tabs” in the context menu, but it is still decent enough.
