It's one of those things you either like it or don't. I personally love puzzles. Sorry. Different strokes for different folks.
But in this case (the school quizzes) it's not even a puzzle. It's google the answers and hope you, as the developer, did your research correctly. You don't even tell us in any way which answers we get wrong or not so there's absolutely no realistic way for players to learn the correct answers other than to google them or just happen to know them beforehand. At least if you told the players what answers they got wrong they could brute force it. The way it is, you absolutely cannot call that THAT a "puzzle", it fulfills NONE of the criteria of what makes something a puzzle. For everything outside of the maths questions it's just a pure guessing game and even within the maths questions there's no way to confirm whether I understood the questions correctly or if maybe you made a mistake. The only feedback we get is that she failed the ENTIRE test, how are we EVER going to figure out what questions we got wrong?? There's a reason that basically everyone is asking with help with these quiz questions, because the way you designed them is honestly obtuse as hell.
And AT THE VERY LEAST, can you remove the write-your-own-answer questions? There's absolutely no way to know which exact answer you're looking for when we have to answer in a text prompt. Do I have to capitalize the name? Should I enter the first name or last name or both? It's just a huge headache as a player and makes my experience significantly less enjoyable.
And I'm not saying any of this as a hater, I genuinely love this title but something like this just completely sours the experience. If I hated this title I would just move on but I genuinely hope you can understand how this particular approach to the school quizzes is a mistake because I only want to see this game be even better.
EDIT::
Case in point: On the 7 wonders question, apparently "Stonehenge" is correct, but this is only correct if you define the 7 wonders according to the "New7Wonders" list which was created in 2001 by a random corporation with no special authority and that isn't the definite list of 7 wonders in any way whatsoever, it's a completely arbitrary list of "7 wonders". Stonehenge HAS in fact been on certain lists of 7 wonders long before, so do you understand why a question like this is nonsense?
Another point: In the "follow the pattern" questions, saying that 6=3 is the correct answer is simplistic rubbish, if you were to actually follow the rules of a real "follow the pattern" question, which are real types of logic questions, the answer should be that 6=6. Having it have to do with the number of letters in the spelling of the number goes completely against how these types of logic questions of "follow the pattern" are supposed to work.
If you're going to have these types of questions and for some reason NOT tell the players what your intended answer is afterwards you simply CANNOT use these kinds of arbitrary questions where your logic or reasoning for your intended answer is just as weak, and in certain cases even weaker, than the logic of other answers that you deem "wrong".
