A few years back I complained because the "planner" our school was asking our children to buy was like this. It was crazy, they want to teach our kids to USE the planner but it's impossible to find the page you want. And the page is so busy it's hard to figure out where to write, and then you only get a tiny amount of space. The thing was 3X bigger than it needs to be. It had all this extraneous stuff about schools and even ads. So the kids they are most desperate to get to use it can't even function with it because it's simply too busy.
Thankfully someone listened because the planner this year is a lot smaller and more streamlines.
6th grade I had to go make a planner for my son that worked better than the stupid one they made...now her uses his calendar on his phone in 9th grade. I said I was going to market my better planner.
